13.1 Formatting a Research Paper

Learning objectives.

• Identify the major components of a research paper written using American Psychological Association (APA) style.
• Apply general APA style and formatting conventions in a research paper.

In this chapter, you will learn how to use APA style , the documentation and formatting style followed by the American Psychological Association, as well as MLA style , from the Modern Language Association. There are a few major formatting styles used in academic texts, including AMA, Chicago, and Turabian:

• AMA (American Medical Association) for medicine, health, and biological sciences
• APA (American Psychological Association) for education, psychology, and the social sciences
• Chicago—a common style used in everyday publications like magazines, newspapers, and books
• MLA (Modern Language Association) for English, literature, arts, and humanities
• Turabian—another common style designed for its universal application across all subjects and disciplines

While all the formatting and citation styles have their own use and applications, in this chapter we focus our attention on the two styles you are most likely to use in your academic studies: APA and MLA.

If you find that the rules of proper source documentation are difficult to keep straight, you are not alone. Writing a good research paper is, in and of itself, a major intellectual challenge. Having to follow detailed citation and formatting guidelines as well may seem like just one more task to add to an already-too-long list of requirements.

Following these guidelines, however, serves several important purposes. First, it signals to your readers that your paper should be taken seriously as a student’s contribution to a given academic or professional field; it is the literary equivalent of wearing a tailored suit to a job interview. Second, it shows that you respect other people’s work enough to give them proper credit for it. Finally, it helps your reader find additional materials if he or she wishes to learn more about your topic.

Furthermore, producing a letter-perfect APA-style paper need not be burdensome. Yes, it requires careful attention to detail. However, you can simplify the process if you keep these broad guidelines in mind:

• Work ahead whenever you can. Chapter 11 “Writing from Research: What Will I Learn?” includes tips for keeping track of your sources early in the research process, which will save time later on.
• Get it right the first time. Apply APA guidelines as you write, so you will not have much to correct during the editing stage. Again, putting in a little extra time early on can save time later.
• Use the resources available to you. In addition to the guidelines provided in this chapter, you may wish to consult the APA website at http://www.apa.org or the Purdue University Online Writing lab at http://owl.english.purdue.edu , which regularly updates its online style guidelines.

General Formatting Guidelines

This chapter provides detailed guidelines for using the citation and formatting conventions developed by the American Psychological Association, or APA. Writers in disciplines as diverse as astrophysics, biology, psychology, and education follow APA style. The major components of a paper written in APA style are listed in the following box.

These are the major components of an APA-style paper:

Body, which includes the following:

• Headings and, if necessary, subheadings to organize the content
• In-text citations of research sources
• References page

All these components must be saved in one document, not as separate documents.

The title page of your paper includes the following information:

• Title of the paper
• Author’s name
• Name of the institution with which the author is affiliated
• Header at the top of the page with the paper title (in capital letters) and the page number (If the title is lengthy, you may use a shortened form of it in the header.)

List the first three elements in the order given in the previous list, centered about one third of the way down from the top of the page. Use the headers and footers tool of your word-processing program to add the header, with the title text at the left and the page number in the upper-right corner. Your title page should look like the following example.

The next page of your paper provides an abstract , or brief summary of your findings. An abstract does not need to be provided in every paper, but an abstract should be used in papers that include a hypothesis. A good abstract is concise—about one hundred fifty to two hundred fifty words—and is written in an objective, impersonal style. Your writing voice will not be as apparent here as in the body of your paper. When writing the abstract, take a just-the-facts approach, and summarize your research question and your findings in a few sentences.

In Chapter 12 “Writing a Research Paper” , you read a paper written by a student named Jorge, who researched the effectiveness of low-carbohydrate diets. Read Jorge’s abstract. Note how it sums up the major ideas in his paper without going into excessive detail.

Write an abstract summarizing your paper. Briefly introduce the topic, state your findings, and sum up what conclusions you can draw from your research. Use the word count feature of your word-processing program to make sure your abstract does not exceed one hundred fifty words.

Depending on your field of study, you may sometimes write research papers that present extensive primary research, such as your own experiment or survey. In your abstract, summarize your research question and your findings, and briefly indicate how your study relates to prior research in the field.

Margins, Pagination, and Headings

APA style requirements also address specific formatting concerns, such as margins, pagination, and heading styles, within the body of the paper. Review the following APA guidelines.

Use these general guidelines to format the paper:

• Set the top, bottom, and side margins of your paper at 1 inch.
• Use double-spaced text throughout your paper.
• Use a standard font, such as Times New Roman or Arial, in a legible size (10- to 12-point).
• Use continuous pagination throughout the paper, including the title page and the references section. Page numbers appear flush right within your header.
• Section headings and subsection headings within the body of your paper use different types of formatting depending on the level of information you are presenting. Additional details from Jorge’s paper are provided.

Begin formatting the final draft of your paper according to APA guidelines. You may work with an existing document or set up a new document if you choose. Include the following:

• Your title page
• The abstract you created in Note 13.8 “Exercise 1”
• Correct headers and page numbers for your title page and abstract

APA style uses section headings to organize information, making it easy for the reader to follow the writer’s train of thought and to know immediately what major topics are covered. Depending on the length and complexity of the paper, its major sections may also be divided into subsections, sub-subsections, and so on. These smaller sections, in turn, use different heading styles to indicate different levels of information. In essence, you are using headings to create a hierarchy of information.

The following heading styles used in APA formatting are listed in order of greatest to least importance:

• Section headings use centered, boldface type. Headings use title case, with important words in the heading capitalized.
• Subsection headings use left-aligned, boldface type. Headings use title case.
• The third level uses left-aligned, indented, boldface type. Headings use a capital letter only for the first word, and they end in a period.
• The fourth level follows the same style used for the previous level, but the headings are boldfaced and italicized.
• The fifth level follows the same style used for the previous level, but the headings are italicized and not boldfaced.

Visually, the hierarchy of information is organized as indicated in Table 13.1 “Section Headings” .

Table 13.1 Section Headings

A college research paper may not use all the heading levels shown in Table 13.1 “Section Headings” , but you are likely to encounter them in academic journal articles that use APA style. For a brief paper, you may find that level 1 headings suffice. Longer or more complex papers may need level 2 headings or other lower-level headings to organize information clearly. Use your outline to craft your major section headings and determine whether any subtopics are substantial enough to require additional levels of headings.

Working with the document you developed in Note 13.11 “Exercise 2” , begin setting up the heading structure of the final draft of your research paper according to APA guidelines. Include your title and at least two to three major section headings, and follow the formatting guidelines provided above. If your major sections should be broken into subsections, add those headings as well. Use your outline to help you.

Because Jorge used only level 1 headings, his Exercise 3 would look like the following:

Citation Guidelines

In-text citations.

Throughout the body of your paper, include a citation whenever you quote or paraphrase material from your research sources. As you learned in Chapter 11 “Writing from Research: What Will I Learn?” , the purpose of citations is twofold: to give credit to others for their ideas and to allow your reader to follow up and learn more about the topic if desired. Your in-text citations provide basic information about your source; each source you cite will have a longer entry in the references section that provides more detailed information.

In-text citations must provide the name of the author or authors and the year the source was published. (When a given source does not list an individual author, you may provide the source title or the name of the organization that published the material instead.) When directly quoting a source, it is also required that you include the page number where the quote appears in your citation.

This information may be included within the sentence or in a parenthetical reference at the end of the sentence, as in these examples.

Epstein (2010) points out that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (p. 137).

Here, the writer names the source author when introducing the quote and provides the publication date in parentheses after the author’s name. The page number appears in parentheses after the closing quotation marks and before the period that ends the sentence.

Addiction researchers caution that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (Epstein, 2010, p. 137).

Here, the writer provides a parenthetical citation at the end of the sentence that includes the author’s name, the year of publication, and the page number separated by commas. Again, the parenthetical citation is placed after the closing quotation marks and before the period at the end of the sentence.

As noted in the book Junk Food, Junk Science (Epstein, 2010, p. 137), “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive.”

Here, the writer chose to mention the source title in the sentence (an optional piece of information to include) and followed the title with a parenthetical citation. Note that the parenthetical citation is placed before the comma that signals the end of the introductory phrase.

David Epstein’s book Junk Food, Junk Science (2010) pointed out that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (p. 137).

Another variation is to introduce the author and the source title in your sentence and include the publication date and page number in parentheses within the sentence or at the end of the sentence. As long as you have included the essential information, you can choose the option that works best for that particular sentence and source.

Citing a book with a single author is usually a straightforward task. Of course, your research may require that you cite many other types of sources, such as books or articles with more than one author or sources with no individual author listed. You may also need to cite sources available in both print and online and nonprint sources, such as websites and personal interviews. Chapter 13 “APA and MLA Documentation and Formatting” , Section 13.2 “Citing and Referencing Techniques” and Section 13.3 “Creating a References Section” provide extensive guidelines for citing a variety of source types.

Writing at Work

APA is just one of several different styles with its own guidelines for documentation, formatting, and language usage. Depending on your field of interest, you may be exposed to additional styles, such as the following:

• MLA style. Determined by the Modern Languages Association and used for papers in literature, languages, and other disciplines in the humanities.
• Chicago style. Outlined in the Chicago Manual of Style and sometimes used for papers in the humanities and the sciences; many professional organizations use this style for publications as well.
• Associated Press (AP) style. Used by professional journalists.

References List

The brief citations included in the body of your paper correspond to the more detailed citations provided at the end of the paper in the references section. In-text citations provide basic information—the author’s name, the publication date, and the page number if necessary—while the references section provides more extensive bibliographical information. Again, this information allows your reader to follow up on the sources you cited and do additional reading about the topic if desired.

The specific format of entries in the list of references varies slightly for different source types, but the entries generally include the following information:

• The name(s) of the author(s) or institution that wrote the source
• The year of publication and, where applicable, the exact date of publication
• The full title of the source
• For books, the city of publication
• For articles or essays, the name of the periodical or book in which the article or essay appears
• For magazine and journal articles, the volume number, issue number, and pages where the article appears
• For sources on the web, the URL where the source is located

The references page is double spaced and lists entries in alphabetical order by the author’s last name. If an entry continues for more than one line, the second line and each subsequent line are indented five spaces. Review the following example. ( Chapter 13 “APA and MLA Documentation and Formatting” , Section 13.3 “Creating a References Section” provides extensive guidelines for formatting reference entries for different types of sources.)

In APA style, book and article titles are formatted in sentence case, not title case. Sentence case means that only the first word is capitalized, along with any proper nouns.

Key Takeaways

• Following proper citation and formatting guidelines helps writers ensure that their work will be taken seriously, give proper credit to other authors for their work, and provide valuable information to readers.
• Working ahead and taking care to cite sources correctly the first time are ways writers can save time during the editing stage of writing a research paper.
• APA papers usually include an abstract that concisely summarizes the paper.
• APA papers use a specific headings structure to provide a clear hierarchy of information.
• In APA papers, in-text citations usually include the name(s) of the author(s) and the year of publication.
• In-text citations correspond to entries in the references section, which provide detailed bibliographical information about a source.

A step-by-step guide for creating and formatting APA Style student papers

The start of the semester is the perfect time to learn how to create and format APA Style student papers. This article walks through the formatting steps needed to create an APA Style student paper, starting with a basic setup that applies to the entire paper (margins, font, line spacing, paragraph alignment and indentation, and page headers). It then covers formatting for the major sections of a student paper: the title page, the text, tables and figures, and the reference list. Finally, it concludes by describing how to organize student papers and ways to improve their quality and presentation.

The guidelines for student paper setup are described and shown using annotated diagrams in the Student Paper Setup Guide (PDF, 3.40MB) and the A Step-by-Step Guide to APA Style Student Papers webinar . Chapter 1 of the Concise Guide to APA Style and Chapter 2 of the Publication Manual of the American Psychological Association describe the elements, format, and organization for student papers. Tables and figures are covered in Chapter 7 of both books. Information on paper format and tables and figures and a full sample student paper are also available on the APA Style website.

Basic setup

The guidelines for basic setup apply to the entire paper. Perform these steps when you first open your document, and then you do not have to worry about them again while writing your paper. Because these are general aspects of paper formatting, they apply to all APA Style papers, student or professional. Students should always check with their assigning instructor or institution for specific guidelines for their papers, which may be different than or in addition to APA Style guidelines.

Seventh edition APA Style was designed with modern word-processing programs in mind. Most default settings in programs such as Academic Writer, Microsoft Word, and Google Docs already comply with APA Style. This means that, for most paper elements, you do not have to make any changes to the default settings of your word-processing program. However, you may need to make a few adjustments before you begin writing.

Use 1-in. margins on all sides of the page (top, bottom, left, and right). This is usually how papers are automatically set.

Use a legible font. The default font of your word-processing program is acceptable. Many sans serif and serif fonts can be used in APA Style, including 11-point Calibri, 11-point Arial, 12-point Times New Roman, and 11-point Georgia. You can also use other fonts described on the font page of the website.

Line spacing

Double-space the entire paper including the title page, block quotations, and the reference list. This is something you usually must set using the paragraph function of your word-processing program. But once you do, you will not have to change the spacing for the entirety of your paper–just double-space everything. Do not add blank lines before or after headings. Do not add extra spacing between paragraphs. For paper sections with different line spacing, see the line spacing page.

Paragraph alignment and indentation

Align all paragraphs of text in the body of your paper to the left margin. Leave the right margin ragged. Do not use full justification. Indent the first line of every paragraph of text 0.5-in. using the tab key or the paragraph-formatting function of your word-processing program. For paper sections with different alignment and indentation, see the paragraph alignment and indentation page.

Page numbers

Put a page number in the top right of every page header , including the title page, starting with page number 1. Use the automatic page-numbering function of your word-processing program to insert the page number in the top right corner; do not type the page numbers manually. The page number is the same font and font size as the text of your paper. Student papers do not require a running head on any page, unless specifically requested by the instructor.

Title page setup

Title page elements.

APA Style has two title page formats: student and professional (for details, see title page setup ). Unless instructed otherwise, students should use the student title page format and include the following elements, in the order listed, on the title page:

• Paper title.
• Name of each author (also known as the byline).
• Affiliation for each author.
• Course number and name.
• Instructor name.
• Assignment due date.
• Page number 1 in the top right corner of the page header.

The format for the byline depends on whether the paper has one author, two authors, or three or more authors.

• When the paper has one author, write the name on its own line (e.g., Jasmine C. Hernandez).
• When the paper has two authors, write the names on the same line and separate them with the word “and” (e.g., Upton J. Wang and Natalia Dominguez).
• When the paper has three or more authors, separate the names with commas and include “and” before the final author’s name (e.g., Malia Mohamed, Jaylen T. Brown, and Nia L. Ball).

Students have an academic affiliation, which identities where they studied when the paper was written. Because students working together on a paper are usually in the same class, they will have one shared affiliation. The affiliation consists of the name of the department and the name of the college or university, separated by a comma (e.g., Department of Psychology, George Mason University). The department is that of the course to which the paper is being submitted, which may be different than the department of the student’s major. Do not include the location unless it is part of the institution’s name.

Write the course number and name and the instructor name as shown on institutional materials (e.g., the syllabus). The course number and name are often separated by a colon (e.g., PST-4510: History and Systems Psychology). Write the assignment due date in the month, date, and year format used in your country (e.g., Sept. 10, 2020).

Title page line spacing

Double-space the whole title page. Place the paper title three or four lines down from the top of the page. Add an extra double-spaced blank like between the paper title and the byline. Then, list the other title page elements on separate lines, without extra lines in between.

Title page alignment

Center all title page elements (except the right-aligned page number in the header).

Title page font

Write the title page using the same font and font size as the rest of your paper. Bold the paper title. Use standard font (i.e., no bold, no italics) for all other title page elements.

Text elements

Repeat the paper title at the top of the first page of text. Begin the paper with an introduction to provide background on the topic, cite related studies, and contextualize the paper. Use descriptive headings to identify other sections as needed (e.g., Method, Results, Discussion for quantitative research papers). Sections and headings vary depending on the paper type and its complexity. Text can include tables and figures, block quotations, headings, and footnotes.

Text line spacing

Double-space all text, including headings and section labels, paragraphs of text, and block quotations.

Text alignment

Center the paper title on the first line of the text. Indent the first line of all paragraphs 0.5-in.

Left-align the text. Leave the right margin ragged.

Block quotation alignment

Indent the whole block quotation 0.5-in. from the left margin. Double-space the block quotation, the same as other body text. Find more information on the quotations page.

Use the same font throughout the entire paper. Write body text in standard (nonbold, nonitalic) font. Bold only headings and section labels. Use italics sparingly, for instance, to highlight a key term on first use (for more information, see the italics page).

Headings format

For detailed guidance on formatting headings, including headings in the introduction of a paper, see the headings page and the headings in sample papers .

• Alignment: Center Level 1 headings. Left-align Level 2 and Level 3 headings. Indent Level 4 and Level 5 headings like a regular paragraph.
• Font: Boldface all headings. Also italicize Level 3 and Level 5 headings. Create heading styles using your word-processing program (built into AcademicWriter, available for Word via the sample papers on the APA Style website).

Tables and figures setup

Tables and figures are only included in student papers if needed for the assignment. Tables and figures share the same elements and layout. See the website for sample tables and sample figures .

Table elements

Tables include the following four elements: 

• Body (rows and columns)
• Note (optional if needed to explain elements in the table)

Figure elements

Figures include the following four elements: 

• Image (chart, graph, etc.)
• Note (optional if needed to explain elements in the figure)

Table line spacing

Double-space the table number and title. Single-, 1.5-, or double-space the table body (adjust as needed for readability). Double-space the table note.

Figure line spacing

Double-space the figure number and title. The default settings for spacing in figure images is usually acceptable (but adjust the spacing as needed for readability). Double-space the figure note.

Table alignment

Left-align the table number and title. Center column headings. Left-align the table itself and left-align the leftmost (stub) column. Center data in the table body if it is short or left-align the data if it is long. Left-align the table note.

Figure alignment

Left-align the figure number and title. Left-align the whole figure image. The default alignment of the program in which you created your figure is usually acceptable for axis titles and data labels. Left-align the figure note.

Bold the table number. Italicize the table title. Use the same font and font size in the table body as the text of your paper. Italicize the word “Note” at the start of the table note. Write the note in the same font and font size as the text of your paper.

Figure font

Bold the figure number. Italicize the figure title. Use a sans serif font (e.g., Calibri, Arial) in the figure image in a size between 8 to 14 points. Italicize the word “Note” at the start of the figure note. Write the note in the same font and font size as the text of your paper.

Placement of tables and figures

There are two options for the placement of tables and figures in an APA Style paper. The first option is to place all tables and figures on separate pages after the reference list. The second option is to embed each table and figure within the text after its first callout. This guide describes options for the placement of tables and figures embedded in the text. If your instructor requires tables and figures to be placed at the end of the paper, see the table and figure guidelines and the sample professional paper .

Call out (mention) the table or figure in the text before embedding it (e.g., write “see Figure 1” or “Table 1 presents”). You can place the table or figure after the callout either at the bottom of the page, at the top of the next page, or by itself on the next page. Avoid placing tables and figures in the middle of the page.

Embedding at the bottom of the page

Include a callout to the table or figure in the text before that table or figure. Add a blank double-spaced line between the text and the table or figure at the bottom of the page.

Embedding at the top of the page

Include a callout to the table in the text on the previous page before that table or figure. The table or figure then appears at the top of the next page. Add a blank double-spaced line between the end of the table or figure and the text that follows.

Embedding on its own page

Embed long tables or large figures on their own page if needed. The text continues on the next page.

Reference list setup

Reference list elements.

The reference list consists of the “References” section label and the alphabetical list of references. View reference examples on the APA Style website. Consult Chapter 10 in both the Concise Guide and Publication Manual for even more examples.

Reference list line spacing

Start the reference list at the top of a new page after the text. Double-space the entire reference list (both within and between entries).

Reference list alignment

Center the “References” label. Apply a hanging indent of 0.5-in. to all reference list entries. Create the hanging indent using your word-processing program; do not manually hit the enter and tab keys.

Reference list font

Bold the “References” label at the top of the first page of references. Use italics within reference list entries on either the title (e.g., webpages, books, reports) or on the source (e.g., journal articles, edited book chapters).

Final checks

Check page order.

• Start each section on a new page.
• Arrange pages in the following order:
• Title page (page 1).
• Text (starts on page 2).
• Reference list (starts on a new page after the text).

Check headings

• Check that headings accurately reflect the content in each section.
• Start each main section with a Level 1 heading.
• Use Level 2 headings for subsections of the introduction.
• Use the same level of heading for sections of equal importance.
• Avoid having only one subsection within a section (have two or more, or none).

Check assignment instructions

• Remember that instructors’ guidelines supersede APA Style.
• Students should check their assignment guidelines or rubric for specific content to include in their papers and to make sure they are meeting assignment requirements.

Tips for better writing

• Ask for feedback on your paper from a classmate, writing center tutor, or instructor.
• Budget time to implement suggestions.
• Use spell-check and grammar-check to identify potential errors, and then manually check those flagged.
• Proofread the paper by reading it slowly and carefully aloud to yourself.
• Consult your university writing center if you need extra help.

Research Paper Format: APA, MLA, & Chicago Style

• Tags: APA , APA Style , Formatting Guidelines

In academia, research papers help us share key findings and valuable knowledge with everyone. Whether you’re in high school, college, or university, you must know how to format a research paper so you can submit a well-organized document.

The three standard formats of research papers widely used in academia are MLA, APA, and the Chicago research paper format. We’ll discuss all three paper formats in detail with actionable tips and guidelines to help you avoid rookie formatting mistakes.

We’ve also added several examples of research paper formats so you can easily learn the proper way to structure and format your research paper. Given below are the three types of research paper formats widely used in academia:

1.  APA format

The American Psychological Association (APA) format is a research paper format popular among scholars, especially in sciences and social sciences. This style emphasizes clarity and conciseness, making it an excellent format for presenting complex scientific ideas in a digestible manner.

Just so we cover all bases, we’ve included plenty of research paper format examples. Take a look!

General guidelines

The  APA paper format follows a set of simple yet strict guidelines to ensure uniformity across different works. Here are some tips on how to format a paper in APA style:

• Double-space all your text.
• Maintain one-inch margins on all sides of the paper.
• Use a font style that is easy to read (typically 12-point Times New Roman).
• Include an APA header on all pages of your paper.
• Make sure each new paragraph is indented by 0.5 inches.

Take a look at this research paper format example outlining the various APA formatting guidelines:

One of the key features of the APA format is its title page. The APA title page serves as the face of your research paper layout, providing essential information about your work. Keep the following in mind:

• Write a title that’s a crisp summary of the paper’s content.
• Mention the author’s name without any titles or degrees.
• Mention the institutional affiliation (the place where the research was conducted).
• Add a header at the top of the page.

Reference page

The reference page is a critical part of the layout of a research paper in the APA style. This page lists all the sources you’ve referenced in your paper. It’s essential for avoiding plagiarism and providing your readers with the opportunity to explore your sources further.

Follow the tips mentioned below when formatting your reference page in APA style:

• Add a “References” label at the top and align it centrally.
• Organize your entries alphabetically based on the last names of the authors.
• Ensure that every entry is double-spaced.
• Acknowledge all sources in the text to maintain transparency in your research process.

Special formatting guidelines

Major headings under APA 7 are bolded and aligned centrally, while the subheadings are indented and end with a period. Subsequent levels of headings are used here:

This format of research papers necessitates a distinct heading structure, facilitating seamless navigation through the different formats. It also implements a unique citation format, guaranteeing that all your references are accurately acknowledged. Major headings are bolded and center-aligned, whereas subheadings are indented and end with a period.

The subsequent levels of headings are used in the APA paper format:

• Level 1: Bold, centered
• Level 2: Bold, left-aligned
• Level 3: Bold italic, left-aligned
• Level 4: Indented, bold
• Level 5: Indented, bold italic

Bonus tip: Titles for tables and figures should be succinct and clear and should be referenced in the text by their respective number. For instance, “As demonstrated in Table 1…”

2.  MLA format

The Modern Language Association (MLA) format is another frequently utilized format for research paper writing, primarily within the humanities. It underscores authorship, making it an excellent choice for papers that concentrate on original analysis.

For the visual learners out there, we’ve added some research paper format examples for your benefit! So, make sure you follow these guidelines while writing your paper.

The general guidelines of the MLA paper writing format are designed to establish a uniform and professional appearance for your work. Follow these steps when formatting your paper in MLA format:

• Use double spacing for your text. 
• Maintain one-inch margins all around.
• Opt for a readable font like 12-point Times New Roman.
• Incorporate a header with your last name and page number on every page.
• Use title case for headings, capitalizing the first letter of each major word.

The MLA paper format doesn’t typically necessitate a separate title page. Instead, the required information is positioned on the first page of the paper, which includes the following:

• Name of the student
• Instructor’s name
• Title of the course
• Date of submission

The title of the paper is presented in the next line, bolded and centered. It’s crucial to ensure that your title is informative and mirrors the content of your research paper.

Bonus tip: Refrain from italicizing, underlining, or bolding the title. Also, don’t use a period after the title.

Works cited page

The “Works Cited” page in the MLA 9 format lists all the sources referenced in your paper. This page plays a crucial role in formatting research papers to avoid plagiarism. While working on your MLA works cited page, keep the following points in mind:

• Start on a new page with the label “Works Cited”, centered and bolded at the top.
• List your entries in alphabetical order by the last names of the authors.
• Make sure each entry is double-spaced.

Remember, the works cited page is not a bibliography. It should only include sources you’ve quoted or paraphrased in your paper!

One of the defining characteristics of the MLA format is its use of parenthetical citations, making the MLA research paper format unique. Instead of footnotes or endnotes, sources are cited in the text using the author’s last name and the page number. For example, (Smith 23). 

Here are some additional guidelines for formatting your paper:

• In-text citations should directly follow the quote or paraphrase, but they should come before the period at the end of the sentence.
• Every major word in the title of a work must be capitalized.

3.  Chicago format

The Chicago Manual of Style (CMOS), or simply the Chicago research paper format , is another commonly used style in academic and professional writing. Preferred by historians, this format offers flexibility and comprehensiveness to accommodate a wide variety of sources.

The general guidelines of the Chicago format are similar to those of the MLA and APA research paper formats, with minor differences. 

Here are the key points to remember about the Chicago paper format:

• Use double spacing for the main text.
• Use single spacing for block quotes, table titles, and figure captions.
• Maintain one-inch margins on all sides for a neat presentation.
• Use a readable font such as Times New Roman, size 12 pt.
• Start page numbers from the second page, and place them in the top right corner.

In the Chicago style, the title page includes the title of the paper, the author’s name, and your course information. Unlike other styles, the title page of a Chicago-formatted paper does not carry a page number or a running head. 

Remember these two things while formatting your Chicago title page:

• Make sure the title is positioned at the center of the page.
• Add your name and class information some lines below the table.

Observe the following example for the Chicago research paper format:

The reference page in the Chicago style is referred to as the “Bibliography”. This page includes all the sources that you’ve cited in your paper.  To correctly format your bibliography, follow the points mentioned below:

• Begin on a new page with the title “Bibliography” centered at the top.
• List your sources in alphabetical order by author’s last name.
• Use a “hanging indent” for each entry (the first line begins at the margin and the following lines are indented).

Bonus Tip: Make sure the bibliography includes all works that were consulted, not just those cited in the text.

One of the unique features of the Chicago style is its use of footnotes or endnotes for citations. When you quote or paraphrase a source, you’ll include a superscript number in the text that corresponds to a note with the citation information.

Here are some additional guidelines to format your paper in the Chicago style:

• Number the footnotes or endnotes consecutively, using Arabic numbers.
• You can be flexible with headings: Either stick to the classic five-level style or create your own.
• Ensure you stay consistent in your approach throughout your paper.

Bonus tip: The first time you’re citing a source, give all the citation info. Feel free to use the short version after that.

Formatting your research paper is much more than just improving aesthetics. It’s about making things easy to read, keeping everything on-brand, and showcasing your attention to detail. Understanding the nitty gritty of the APA, MLA, or Chicago research paper formats is essential to producing high-quality and well-organized research papers.

Writing a research paper can be daunting if you’re not experienced with the process. Getting the proper format is one of the most challenging aspects of the task. Reviewers will immediately dismiss a paper that doesn't comply with standard formatting, regardless of the valuable content it contains. 

In this article, we'll delve into the essential characteristics of a research paper, including the proper formatting.

Make research less tedious

Dovetail streamlines research to help you uncover and share actionable insights

• What is a research paper?

A research paper is a document that provides a thorough analysis of a topic , usually for an academic institution or professional organization. A research paper may be of any length, but they are typically 2,000–10,000 words. 

Unlike less formal papers, such as articles or essays, empirical evidence and data are key to research papers. In addition to students handing in papers, scientists, attorneys, medical researchers, and independent scholars may need to produce research papers.

People typically write research papers to prove a particular point or make an argument. This could support or disprove a theoretical point, legal case, scientific theory, or an existing piece of research on any topic. 

One of the distinguishing characteristics of research papers is that they contain citations to prior research. Citing sources using the correct format is essential for creating a legitimate research paper. 

• Top considerations for writing a research paper

To write a research paper, you must consider several factors. Fields such as the sciences, humanities, and technical professions have certain criteria for writing research papers. 

You’ll write a research paper using one of several types of formatting. These include APA, MLA, and CMOS styles, which we’ll cover in detail to guide you on citations and other formatting rules. 

Specific requirements of the assignment

If the paper is for a college, university, or any specific organization, they’ll give you certain requirements, such as the range of topics, length, and formatting requirements.

You should study the specifics of the assignment carefully, as these will override more general guidelines you may find elsewhere. If you're writing for a particular professor, they may ask for single or double spacing or a certain citation style. 

• Components of a research paper

Here are the basic steps to writing a quality research paper, assuming you've chosen your topic and considered the requirements of the paper. Depending on the specific conditions of the paper you're writing, you may need the following elements:

Thesis statement

The thesis statement provides a blueprint for the paper. It conveys the theme and purpose of the paper. It also informs you and readers what your paper will argue and the type of research it will contain. As you write the paper, you can refer to the thesis statement to help you decide whether or not to include certain items.

Most research papers require an abstract as well as a thesis. While the thesis is a short (usually a single sentence) summary of the work, an abstract contains more detail. Many papers use the IMRaD structure for the abstract, especially in scientific fields. This consists of four elements:

Introduction : Summarize the purpose of the paper

Methods : Describe the research methods (e.g., collecting data , interviews , field research)

Results: Summarize your conclusions.  

Discussion: Discuss the implications of your research. Mention any significant limitations to your approach and suggest areas for further research.

The thesis and abstract come at the beginning of a paper, but you should write them after completing the paper. This approach ensures a clear idea of your main topic and argument, which can evolve as you write the paper.

Table of contents

Like most nonfiction books, a research paper usually includes a table of contents. 

Tables, charts, and illustrations

If your paper contains multiple tables, charts, illustrations, or other graphics, you can create a list of these. 

Works cited or reference page

This page lists all the works you cited in your paper. For MLA and APA styles, you will use in-text citations in the body of the paper. For Chicago (CMOS) style, you'll use footnotes. 

Bibliography

While you use a reference page to note all cited papers, a bibliography lists all the works you consulted in your research, even if you don't specifically cite them. 

While references are essential, a bibliography is optional but usually advisable to demonstrate the breadth of your research.

Dedication and acknowledgments

You may include a dedication or acknowledgments at the beginning of the paper directly after the title page and before the abstract.

• Steps for writing a research paper

These are the most critical steps for researching, writing, and formatting a research paper:

Create an outline

The outline is not part of the published paper; it’s for your use. An outline makes it easier to structure the paper, ensuring you include all necessary points and research. 

Here you can list all topics and subtopics that will support your argument. When doing your research, you can refer to the outline to ensure you include everything. 

Gather research

Solid research is the hallmark of a research paper. In addition to accumulating research, you need to present it clearly. However, gathering research is one of the first tasks. If you compile each piece of research correctly, it will be easier to format the paper correctly. You want to avoid having to go back and look up information constantly.

Start by skimming potentially useful sources and putting them aside for later use. Reading each source thoroughly at this stage will be time-consuming and slow your progress. You can thoroughly review the sources to decide what to include and discard later. At this stage, note essential information such as names, dates, page numbers, and website links. Citing sources will be easier when you’ve written all the information down.

Be aware of the quality of your sources. A research paper should reference scholarly, academic, or scientific journals. It’s vital to understand the difference between primary and secondary sources. 

A primary source is an original, firsthand account of a topic. A secondary source is someone else covering the topic, as in a popular article or interview. While you may include secondary sources, your paper should also include primary research . Online research can be convenient, but you need to be extra careful when assessing the quality of your sources.

Write the first draft

Create a first draft where you put together all your research and address the topic described in your thesis and abstract. 

Edit and format the paper

Proofread, edit, and make any necessary adjustments and improvements to the first draft. List your citations as described below. Ensure your thesis and abstract describe your research accurately. 

• Formatting a research paper: MLA, APA, and CMOS styles

There are several popular formats for research papers: MLA (Modern Language Association) and APA (American Psychological Association). Certain academic papers use CMOS (Chicago Manual of Style). Other formats may apply to particular fields. 

For example, medical research may use AMA (American Medical Association) formatting and IEEE (Institute of Electrical and Electronics Engineers) for particular technical papers. The following are the guidelines and examples of the most popular formats:

The humanities typically use MLA format, including literature, history, and culture. Look over examples of papers created in MLA format . Here are the main rules to keep in mind:

Double-spaced lines.

Indent new paragraphs 1/2 inch.

Title case for headings, where all major words are capitalized, as in "How to Write a Research Paper." 

Use a popular font such as Times New Roman. This applies to all formatting styles.

Use one-inch margins on all sides. 

Number sections of the paper using Arabic numerals (1, 2, 3, etc.). 

Use a running head for each page on the upper right-hand corner, which consists of your last name and the page number.

Use an in-text citation within the text, using the author's last name followed by the page number: "Anything worth dying for is certainly worth living for" (Heller 155).  

On the citations page, list the full name, book or periodical, and other information. For MLA, you will not need footnotes, only in-text citations.

List citations in alphabetical order on a separate page at the end of the paper entitled “Works Cited.” 

Continuing with the above example from Heller, the listing would be: Heller, Joseph. Catch-22, Simon & Schuster, 1961.

For a periodical, the format is "Thompson, Hunter S. "The Kentucky Derby is Decadent and Depraved" Scanlon's, June 1970."

Use title case for source titles, as in "On the Origin of Species."

The sciences typically use APA format, including physical sciences such as physics and social sciences such as psychology. Simply Psychology provides examples of APA formatting . The following are the most important rules of the APA format.

Begin the paper with a title page, which is not required for MLA.

Use double-line spacing.

Use a running head for each page in the upper right-hand corner, which consists of the paper's title in capital letters followed by the page number.

The citations page at the end should be titled "References."

In-text citations should include the publication date: (Smith, 1999, p. 50). Note also that there's a "p" for "page," whereas in MLA, you write the page number without a "p."

As with MLA, use title case for headings, as in "Most Popular Treatments for Cognitive Disorders."

Use sentence case for titles of sources, as in "History of the decline and fall of the Roman empire." Note "Roman" starts with a capital because it's a proper noun.  

When citing in-text references, use the author's last name and the first and middle initials. 

Always use the Oxford comma. This comma goes before the words "or" and "and" in a list. For example, "At the store, I bought oranges, paper towels, and pasta."

CMOS formatting

Book publishers and many academic papers use CMOS formatting based on the Chicago Manual of Style. CMOS is also called Turabian, named after Kate L. Turabian, who wrote the first manual for this style. Here are examples of CMOS style formatting and citations.

Include an unnumbered title page.

Place page numbers on the upper right-hand corner of the page. Do not list your name or the paper's title as you would for MLA or APA styles.

Use title case for both headings and sources (same as MLA).

Unlike MLA and APA, the Chicago style uses footnotes for citations. Use a superscript for footnotes: "Smith argues against Jones' theory¹.” Footnotes may appear at the bottom of the page or the end of the document.  

CMOS supports both short notes and full notes. In most cases, you'll use the full note: "Michael Pollan, The Omnivore's Dilemma: A Natural History of Four Meals (New York: Penguin, 2006), 76." For further references to the same source, use a short note: " Pollan, Omnivore's Dilemma, 45." The requirements of some papers may specify using only short notes for all footnotes.

• General guidelines for writing and formatting research papers

Keep these guidelines in mind for all types of research papers:

Initial formatting

As you create your first draft, don't worry about formatting. If you try to format it perfectly as you write the paper, it will be difficult to progress and develop a flow of thought. With the first draft, you don't have to be concerned about ordering the sections. You can rearrange headings and sections later. 

Citation tools

Use automation tools for citations . Some useful tools make citations easier by automatically generating a citation list and bibliography. Many work with APA, MLA, and CMOS styles.

Check for plagiarism

Use a plagiarism detector to make sure your paper isn't unintentionally plagiarizing. There are many free and paid plagiarism checkers online, such as Grammarly. 

Proofread your work

Do several rounds of editing and proofreading. Editing is necessary for any type of writing, but you’ll need to revisit several distinct areas with a research paper:

Check for spelling and grammatical errors.

Read the paper to make sure it's well-argued and that you’ve organized it properly. 

Check that you’ve correctly formatted citations. It's easy to make errors, such as incorrect numbering of footnotes (e.g., Chicago style) or forgetting to include a source on your citations page.

30 Editable Research Paper Templates (MLA Formats)

A research paper template is a document that contains research questions, variable interpolation, thesis, methodology, and results evaluation. To create an effective research paper, make sure that everything you present comes from reliable sources.

Research Paper Templates

What is a research paper.

In most cases, a research paper template is a piece of academic writing that contains analysis, argument, and interpretation based on independent comprehensive research. A research MLA format template is a lot like academic essays except that these are typically longer and have more details.

These assess your academic writing skills along with your scholarly research skills. To write this document, you need:

• To show a strong knowledge of the topic.
• The ability to use various resources.
• To make an original contribution through your writing.

Career Research Papers

What are the 5 parts of research paper.

One thing worth remembering about a student or career research paper is that you should base it on an hourglass structure. To do this, you need to include the important parts of this document:

• Introduction This is the first part where you set the direction of your paper by making an exact outline of what you want to achieve. Although for many, this is the initial step, others save writing the introduction for last because it serves as a quick summary of their document. Either approach is fine and is usually a matter of preference. As long as you plan a logical structure for the parts of the research paper, you can use either method.
• Method Many consider this as the easiest part of the document to write because it is simply a rundown of the methodology and design used to conduct your research. The exact methodology may vary depending on the exact kind of experiment or field of research.
• Results Depending on the results and objectives of your experiment, this is the most variable section of your paper. For quantitative research, you would present numerical data and results. For qualitative research, it involves a broader discussion without giving too many unnecessary details.
• Discussion All information in your discussions should be directly related to your thesis statement. Otherwise, you will risk creating cluttered findings. Just stick with the hourglass principle where you expand on your topic in the next section.
• Conclusion In this section, you build your discussion by trying to relate your findings to other studies and research or to the real world. In a shorter research paper, you may only have a conclusion of just 1 to 2 paragraphs or even just a couple of lines.

In addition, a complete research paper template should always have a reference list where you document all of the sources you used. Format this according to MLA, APA or some other academic format .

College Research Papers

How do you write a research paper.

You can use these steps as a guide when writing a college research paper or a scientific research paper template:

• Familiarize yourself with the assignment Allot ample time to go over your assignment. Consider every bit of information that your instructor has given. Carefully go through the assignment, grading rubric, prompts, and other related materials. To keep track of all the important notes in each of the sources, highlight them or take notes .
• Choose a topic After understanding what you have to write about in your research paper template, the next step is to decide the topic. This could be a challenging undertaking but it shouldn’t discourage you. Choose a topic you’re passionate about or interested in without having to worry about finding the “perfect topic.”
• Research You should always base your research on reliable resources. That way, you won’t run into any issues after you have submitted your completed research paper template for review.
• Organize your research What comes next once you have gathered all the information needed to write your paper? The next step is about getting things organized. Like any other research, various people have various preferences. It may also depend on your assignment. For instance, having some sort of bibliography can be very helpful when it comes to organizing your research.
• Form your thesis This is simply a short statement that you, as the researcher, would put forward for the readers of your paper as to what you’re trying to prove or explain.
• Come up with an outline As in a bibliography, how you will create an outline depending on your assignment. Even if an outline isn’t required, it can still be a very useful tool.
• Write the content After completing all of the previous steps, you are now ready to write your research paper. Some think that they should have begun to write the paper sooner and that all the preliminaries are not that necessary. This is a wrong assumption. Everything you have accomplished up to this point is essential as the preparations will help you come up with a clear, interesting, and strong research paper.
• Edit the content This means examining your paper’s organization, structure, length, and wording. If your paper is either too short or too long, you need to revise it by either building it up or cutting it down to a more acceptable length. Just be very careful when making these edits. If there is a need to add more content, don’t just add words randomly or repeat the information you have stated already. Identify areas where you can expand or what you can include that still fits in with the rest of the content. You can also choose to further the ideas you have presented or add valuable information to concepts you have explained.
• Check the grammar Another important part of the process is to check your grammar. This may seem difficult but there are resources and tools that you can use to perform this task. These tools offer editing for substance, editing for grammar, and so on. If you think you need to take a break before checking, take a break. This could refresh your mind and you might even come back feeling more focused. This is important so that you can catch and fix errors in your document.
• Proofread before submitting After checking your research paper, you can re-read it again just to make sure that your paper delivers everything your assignment asks for. When you have polished and improved it enough, it’s for you to submit.

Research papers are a cornerstone of academic growth, serving as a critical tool for students to delve deep into subject matters, enhance their analytical skills, and contribute to academic discourse.

See also What Is The Writing Process?

Let’s try to demystify the process of writing a research paper by providing a clear, step-by-step approach that can be adapted to any academic level or subject. Planning and organization can make writing a research paper less daunting. Students are encouraged to confidently approach this intellectual journey, using this guide as a roadmap to navigate the complexities of research writing.

The first step in any academic writing project, particularly a research paper, is to understand the assignment thoroughly. Misunderstanding the prompt can lead to significant missteps down the line. It’s important to read the assignment prompt carefully and use it to plan your paper. Students should consider consulting a paper writing service to guide interpreting complex instructions or academic expectations. Essential questions to ask include: What is the purpose of the paper? Who is the audience? What is the required scope and format?

• Understanding the Assignment

Selecting a topic is more than just picking an area of interest; it involves balancing personal curiosity with academic value and resource availability. A good topic should allow you to explore questions or issues you care about while meeting the assignment’s requirements. Strategies for topic selection include brainstorming, preliminary reading, and discussing ideas with peers or instructors.

• Conducting Preliminary Research

Begin with general sources to gain an overview of your topic’s broader context. This can include textbooks, encyclopedias, or reliable online resources. Identify key themes, concepts, and terminology relevant to your subject during this phase.

As you gather more information, start focusing your research on a specific aspect of the topic. This will help you develop a focused research question or a strong thesis statement that will guide the rest of your research and writing process.

• Developing a Research Plan

Determine what types of sources are most appropriate for your topic. This might include books, peer-reviewed journal articles, interviews, or primary documents. Plan a realistic timeline for your research and writing, setting key milestones to ensure steady progress.

Use digital tools such as citation management software, note-taking apps, and organizational platforms to organize your research. These tools can help manage sources, keep track of important quotes, and structure your paper’s outline.

• Conducting In-Depth Research

Distinguish between scholarly and non-scholarly sources. Utilize academic databases and libraries to access credible and relevant material. Internet sources should be cautiously approached and evaluated for credibility and relevance.

Learn to assess the reliability, bias, and usefulness of each source. Critical reading and analytical note-taking are essential at this stage to ensure that you gather strong evidence to support your thesis.

• Crafting a Strong Thesis Statement

A thesis statement is a concise summary of your paper’s main point or claim. It is typically one sentence long and states your position clearly. The thesis is crucial as it guides the structure and argumentation of your research paper.

As your research progresses, revisit and possibly refine your thesis statement to reflect deeper insights and stronger evidence. This may involve tightening its focus, adjusting its angle, or strengthening its argumentative power. Examples of effective thesis statements will illustrate how specificity and clarity contribute to a compelling argument.

• Creating an Outline

An outline is a blueprint for your paper; it organizes your thoughts and lays out the structure of your argument coherently. This helps prevent structural issues later in the writing process and ensures that each part of your argument flows logically into the next.

Start by outlining the main points of your introduction, body, and conclusion. Under each main point, list subpoints and supporting evidence, which can be detailed from your research that backs up your thesis. Consulting an online paper writing service can provide additional structure and guidance for students feeling overwhelmed by this stage.

• Writing the First Draft

Begin writing with the body of your paper, as it contains the bulk of information and analysis. Don’t worry about getting everything perfect on the first try. The goal is to put your research and ideas into a coherent structure.

Keep your writing clear and focused. Employ a mix of summarization, direct analysis, and critical thinking. Ensure that each paragraph opens with a clear topic sentence and closes with a transition to the next idea, ensuring smooth, logical flow.

• Revising and Editing

Once your first draft is complete, take time to revise it thoroughly. Look for ways to strengthen your argument, clarify your points, and improve the overall flow of the paper. Ensure that each section contributes directly to supporting your thesis. Don’t hesitate to rewrite sections for better clarity and impact if necessary.

After revising the content, focus on grammar, punctuation, and style. Look for mistakes like misplaced commas, incorrect verb tenses, or inconsistent formatting. Using tools from the best paper writing service can help ensure your paper meets academic standards.

• Formatting and Citations

Please familiarize yourself with the required citation style for your paper, whether it’s APA, MLA, Chicago, or another format. Proper citation is crucial to avoid plagiarism and to give proper credit to the sources of your research.

Ensure your paper is formatted correctly according to your assignment requirements. This includes setting the correct margins, using the appropriate font size, and including all necessary sections like a title page, headings, and a bibliography. Many students find this step meticulous; however, a paper writer skilled in formatting can assist in polishing the final document.

• Final Proofreading and Submission

Carefully proofread your paper to catch any lingering errors and ensure it reads smoothly. Techniques such as reading aloud or having a peer review of your work can be invaluable. Check for consistency in your arguments, accuracy in your information, and completeness in your research.

Create a checklist for all elements needed for submission, including additional materials like appendices or abstracts. Ensure everything is in order before you submit your paper, whether online or in person. Double-check that all guidelines are followed to avoid last-minute surprises.

Writing a research paper is a demanding but rewarding process. By following these steps, students can produce well-organized, insightful, and high-quality research papers that meet academic standards and enhance their understanding and expertise in the chosen subject area.

Remember, using resources such as a paper writing service should complement your efforts and provide support as you develop your skills as a researcher and writer. Dedication and attention to detail make the journey from a blank page to a completed research paper a significant academic achievement.

An outline is a tool to organize written ideas about a topic or thesis logically. Outlines arrange major topics, subtopics, and supporting details. Writers use outlines when writing their papers to know which topic to cover in what order. Outlines for papers can be very general or very detailed. Check with your instructor to understand what is expected of you.

Alphanumeric Outline

I.      Roman Numerals

A.    I, II, III, IV, V, VI, VII, VIII, IX, X, etc.

B.    Represent main ideas to be covered in the paper in the order they will be presented

II.    Uppercase Letters

A.   A, B, C, D, E, F, G, H, I, J, K, L, etc.

B.    Represent subtopics within each main idea

III.       Arabic Numbers

   A.    1, 2, 3, 4, 5, 6, 7, 8, 9, 10, etc.

   B.    Represent details or subdivisions within subtopics

IV.    Lowercase Letters

   A.    a, b, c, d, e, f, g, h, i, j, l, m, etc.

   B.    Represent details within subdivisions

Full-sentence outline

• Each roman numeral (I, II, III, IV…) indicates the start of a new paragraph. So I. is the first sentence of the introduction, II. is the first sentence of the first paragraph of the body, III. is the first sentence of the second paragraph of the body, and so on.
•  Each capital letter (A, B, C, D…) indicates a main point within the structure of the paragraph. So in our introduction, A. is the attention getter, B. is another attention getter, C. describes a point that makes the topic personal, and D. is the thesis statement.
• Each Arabic numeral (1, 2, 3, 4…) indicates a sentence or piece of supporting evidence for each main point. So in the first body paragraph (II.), point A. is a general statement that needs some additional support, so 1. provides a supporting statement of fact and the citation of where that information came from. 2. provides another sentence with supporting evidence, as does 3.

There are no formal APA guidelines for creating an outline. We recommend you follow standard  APA formatting rules for accepted fonts, double spacing, one-inch margins, page numbers, and header . A cover or title page should also be included if you are handing in the outline as an assignment. Include a References page if outside resources are used while drafting your outline.

Here's why students love Scribbr's proofreading services

Discover proofreading & editing

The title page of your thesis or dissertation should include your name, department, institution, degree program, and submission date.

Usually, no title page is needed in an MLA paper . A header is generally included at the top of the first page instead. The exceptions are when:

• Your instructor requires one, or
• Your paper is a group project

In those cases, you should use a title page instead of a header, listing the same information but on a separate page.

The title page of your thesis or dissertation goes first, before all other content or lists that you may choose to include.

In most styles, the title page is used purely to provide information and doesn’t include any images. Ask your supervisor if you are allowed to include an image on the title page before doing so. If you do decide to include one, make sure to check whether you need permission from the creator of the image.

Include a note directly beneath the image acknowledging where it comes from, beginning with the word “ Note .” (italicized and followed by a period). Include a citation and copyright attribution . Don’t title, number, or label the image as a figure , since it doesn’t appear in your main text.

At the origin of the Universe, an asymmetry between the amount of created matter and antimatter led to the matter-dominated Universe as we know it today. The origins of this asymmetry remain unknown so far. High-energy nuclear collisions create conditions similar to the Universe microseconds after the Big Bang, with comparable amounts of matter and antimatter 1 , 2 , 3 , 4 , 5 , 6 . Much of the created antimatter escapes the rapidly expanding fireball without annihilating, making such collisions an effective experimental tool to create heavy antimatter nuclear objects and to study their properties 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , hoping to shed some light on the existing questions on the asymmetry between matter and antimatter. Here we report the observation of the antimatter hypernucleus \({}_{\bar{\Lambda }}{}^{4}\bar{{\rm{H}}}\) , composed of a \(\bar{\Lambda }\) , an antiproton and two antineutrons. The discovery was made through its two-body decay after production in ultrarelativistic heavy-ion collisions by the STAR experiment at the Relativistic Heavy Ion Collider 15 , 16 . In total, 15.6 candidate \({}_{\bar{\Lambda }}{}^{4}\bar{{\rm{H}}}\) antimatter hypernuclei are obtained with an estimated background count of 6.4. The lifetimes of the antihypernuclei \({}_{\bar{\Lambda }}{}^{3}\bar{{\rm{H}}}\) and \({}_{\bar{\Lambda }}{}^{4}\bar{{\rm{H}}}\) are measured and compared with the lifetimes of their corresponding hypernuclei, testing the symmetry between matter and antimatter. Various production yield ratios among (anti)hypernuclei (hypernuclei and/or antihypernuclei) and (anti)nuclei (nuclei and/or antinuclei) are also measured and compared with theoretical model predictions, shedding light on their production mechanisms.

The arrows indicate the relation between variables and their corresponding geometric distances.

Extended Data Fig. 2 Reconstruction efficiency as a function of L /( β γ ) obtained from the embedding Monte Carlo technique.

Hypernuclei have stricter topological cuts than antihypernuclei to suppress knock-out 3 He and 4 He, resulting in lower efficiencies.

Extended Data Fig. 3

\({}_{\Lambda }{}^{3}{\rm{H}}\) , \({}_{\bar{\Lambda }}{}^{3}\bar{{\rm{H}}}\) , \({}_{\Lambda }{}^{4}{\rm{H}}\) and \({}_{\bar{\Lambda }}{}^{4}\bar{{\rm{H}}}\) candidate invariant-mass distributions in different L / β γ intervals.

Extended Data Fig. 4 d N / d ( L / β γ ) as a function of L / β γ for Λ and \(\bar{\Lambda }\) .

The exponential fits are applied to obtain their lifetimes.

Extended Data Fig. 5 Efficiency corrected p T spectra for 3 He, \({}^{3}\bar{{\rm{He}}}\) , \({}_{\Lambda }{}^{3}{\rm{H}}\) , and \({}_{\bar{\Lambda }}{}^{3}\bar{{\rm{H}}}\) .

The spectra are in the phase space of ∣ y ∣  < 0.7 with only minimum-bias triggered events. The spectra are not normalized by the number of events. The lines represent the BW-function fits.
