All users must be registered to JHEP. Registration gives access to your personal pages for all the roles you play in the journal (author, referee, editor). There you can perform all the actions connected with the stages in the editorial procedure. Registration is easy and free of charge. To register you have to fill in the form on the JHEP home page with the following data:

• Login name
• Password
• First Name
• Last Name
• E-mail
• Institution

If you cannot remember your registration data, please do not register again, just click on "automatic password recovery" on the JHEP home page. You can also update your profile and change login name and password by clicking on "modify my personal data".

The checkbox "Remember my login name on this computer" allows a cookie to be sent to your computer, which spares you from having to log in every time, unless you click on the "logout" button.

For information on the status of your submission please use the "WRITE TO EDITOR" or the "WRITE TO EDITORIAL OFFICE" buttons available at the bottom of the preprint page on your author pages (this link will only be accessible from the JHEP home page once you have submitted your contribution as a corresponding author). Please ALWAYS use these tools instead of normal e-mail so that these messages may be saved in the database and associated to the document they refer to.

On your author pages you can find all your pending preprints divided into sections according to their status:

• Waiting for editor's decision: Your submissions that are still being considered for publication. Any revised preprint that you have sent following editor's request can be found here.
• To be revised (major revision): preprints that you have to revise and resubmit from your Author pages.
• To be revised (minor revision): preprints for which you have to make some small modifications prior to acceptance. The contribution will not be labelled as "revised" when it is published.
• To proofread: accepted preprints that have been typeset in the JHEP style, and must be proof-read by you before publication.
• Appeals against rejection: rejected preprints that the editor has accepted to reconsider for publication.

Furthermore, in the top part of the page there are two navigation bars. The bottom one leads to all archived contributions, which are divided into

• Accepted: accepted preprints that have not (yet) been published
• Rejected: preprints that have not been accepted for publication
• Withdrawn: preprints withdrawn
• Not suitable: preprints considered as not suitable for the journal
• Published: papers published.

Title, Authors (first and family names), affiliations and e-mail addresses must be clearly indicated.

The abstract should briefly summarize the content of the contribution and must fit in the first page.

Please avoid formulae and references in the title and abstract.

At the time of submission you must characterise your work with a number of keywords selected from the JHEP keyword list. Please indicate these keywords after the abstract.

Please divide the text into sections. Write your work in standard, comprehensible English. Conciseness is strongly encouraged, but clarity and consistency are more important. Short and simple words and sentences are helpful for readers. Please keep jargon and acronyms to a minimum. The Editors will consider whether the content is of sufficient scientific interest compared to the overall length and may recommend ways of shortening the text.

Tables and figures can be used to improve the information in the text. Tables and figures should be referenced in the text and always have a caption describing their contents. The minimum resolution requested for figures is 150 and the maximum one should not exceed 250 dpi. Vector images containing fonts must have the fonts embedded in the files.

If you include pictures or other material that has already been published elsewhere, please obtain permission from the copyright owner(s) before incorporating it in your article

Particularly large tables and figures or other electronic supplementary material (animations, Mathematica files, etc.) can be submitted as attachments to a preprint. It is possible to submit more than one attachment recursively, clicking on the "upload file" button after the successful submission of your preprint. For each work you wish to attach, please fill in the form and provide a title, a caption describing the content of the file and choose the category of file that you are attaching (Figure, Table, Video or, generically, Attachment).

To accommodate user downloads, please keep in mind that the file-size affects the download time.

Any supplementary material attached will be available to reviewers and, in case of acceptance, will not be typeset or transformed in any way. To ensure that editors, referees and readers may be able to view the files attached, authors are kindly requested to prepare them using standard formats.

If you wish to include material that has already been published elsewhere, please obtain permission from the copyright owner(s) before incorporating it in your article.

The full text of manuals and computer codes cannot be meaningfully included in published papers as these can be extremely lengthy and therefore cumbersome. As a general rule, manual and computer codes should be attached (see above section Supplementary material attached). Alternatively, papers should include a link to a website where the code or manual can be viewed or downloaded.

JHEP uses the sequential numerical system for references in the text. The sequential numbers occur within square brackets, and the reference list at the end of the preprint lists the references in numerical order, not alphabetical.

Each item of the bibliography should cite one work only; articles on the same topic or different volumes of one book, should be referenced by separate bibliography items. Phrases introducing cited work (e.g. "See for example") should not be included within the reference in the bibliography but may be used as part of the text introducing the citation ("See for example [1,2,5,6]"). If you need to refer to a part of one reference (e.g. "See chapter N of..."), please do it inside the text, not in the bibliography ("See chapter N of [1]"). Should your bibliography not meet this requirement upon acceptance of your paper, it will have to be corrected during the typesetting stage, which might lead to a longer proofreading stage.

The information provided for each reference should be as complete as possible:

• articles: author(s), title, journal name, volume, year, page number, arxiv-number. Additional information (erratum, addendum) can be specified too. For example:

  M. Anselmino, A. Efremov and E. Leader, The theory and phenomenology of polarized deep inelastic scattering, Phys. Rept. 261 (1995) 1 [Erratum ibid 281 (1997) 399] [hep-ph/9501369]

  
  
• books: author(s), title, publisher and year. For example:

  R. Penrose and W. Rindler, Spinors and Space-time, Vol. 2: Spinor and twistor methods in space-time geometry, Cambridge University Press, Cambridge U.K. (1986), pg. 501

  
  
• technical report/note: author(s), title, report number. For example:

  CMS collaboration, Technical Design Report Vol. 1, CERN-LHCC-2006-001

  
  
• proceeding/talk: author(s), title, conference information, year. For example:

  HERMES collaboration, F.~Ellinghaus, DVCS at HERMES: Recent Results, in Proceedings of the Workshop on Exclusive Reactions at High Momentum Transfer, Jefferson Lab, Newport News, U.S.A., May 2007

  
  

Manuscripts can be prepared in TeX/LaTeX or in pdflatex and will be automatically transformed by the system in PDF files.

Your contribution can be one of the following:

1. a single .tex file
2. a file archive (.zip or .tar.gz)
   If your preprint includes more than one file, these will have to be archived. Please make sure the master file is saved in the root (main) directory. The archive should contain only the files necessary for the compilation and the production of the pdf. Other files (cover letters, reply to referee reports, etc.) must not be included since the system would simply ignore them.

Manuscripts should be preferably prepared in LaTeX using the jheppub package. Other macro packages are also accepted, but preprints in these formats are inevitably processed more slowly after acceptance. If you are using other LaTeX formats, you should try to use standard packages. Some frequently used macro packages, (i.e.: aastex, elsart, feynman, harvmac, lanlmac, j-phys, phyzzx and revtex), even if old and/or deprecated, are installed at the JHEP site, in addition to the standard TeX inputs. If you are using an unrecognised package, please include it in making the submission. Always consider that the submission can be completed only if your file compiles successfully on the JHEP server. If you have used BibTeX, you must include the .bbl file. The .bib file may also help. Figures must be in PostScript format (.eps or .ps). If you use packages like feynmf that require the use of metafont please include the .pk, .tfm and .t1, .t2, ... files in your archive.

If the document consists of a stand-alone (La)TeX file this alone can be submitted as it is, without compressing it.

You can also submit pdflatex documents which allows you to use .pdf, .png and .jpg images. To ensure pdflatex compilation you must add \pdfoutput=1 in the line immediately after the \documentclass command as shown in the following example:

\documentclass[11pt,a4paper]{article}
\pdfoutput=1
...

Note that in this case .ps and .eps images are not allowed.

Preprints can be submitted only via the SISSA website by authors previously registered to JHEP. The person making the submission (corresponding author) must be one of the authors. To register to JHEP please read the instructions in the section General.

Submission to JHEP implies that:

• the work described has not been published before (except in form of non- peer-reviewed preprint material, as an abstract or as part of a published lecture, review or thesis);
• it is not under consideration for publication, and will not be published, in any other commercial and/or refereed publication;
• its publication has been approved by all co-authors, if any, as well as - tacitly or explicitly - by the responsible authorities at the institution where the work was carried out;
• the author warrants that his/her contribution is original and that he/she has full power to make this grant;
• the paper will not be published if the copyright transfer is not accepted.

In order to submit a new preprint please login to JHEP. There are two ways to submit a contribution.

If you have already posted your paper on the arXiv, then you can submit it to JHEP just by selecting the keywords and sending the arXiv-number. This facility only works for TeX/LaTeX files. To submit your contribution please follow the following steps:

You are first requested to select the appropriate keywords to characterise your work. Please choose from 2 to 4 keywords for theoretical papers, only 1 keyword for experimental papers and no more than 2 for phenomenological papers. Make sure your selection is accurate because the keywords will be used to automatically identify the most suitable editor-in-charge for your submission. Requests for changing keywords after the submission has been completed will not be accepted.

After you have chosen the keywords, press the button "Submit" at the bottom of the page.

You can now select the appropriate archive and fill in the arXiv reference to your contribution and click on "submit". The system will take care of downloading the file(s) together with the full metadata. Please DO NOT double-click: push the upload button just once, and please wait. The system is processing your files. This can take about one minute or more depending on their size.

Please note that if two or more source files have the same .tex extension (i.e. "abc.tex" and "def.tex"), in making the submission you must specify the master file name in the appropriate field, otherwise the submission will fail.

After completing the procedure, a submission report will be shown to you with the data of your contribution and the link where you can upload additional materials (the "upload file" button. For further infromation, see the section Supplementary material attached). If, on the other hand, the submission fails the report will inform you of the error(s) that have occurred. In particular if the (La)TeX compilation fails, please read the .log file, fix the error on your computer and try again. Should you be unable to solve the problem, do contact the Editorial Office.

To prepare your files for submission, please read the section File preparation.

You are first requested to select the appropriate keywords to characterise your work. Please choose from 2 to 4 keywords for theoretical papers, only 1 keyword for experimental papers and no more than 2 for phenomenological papers. Make sure your selection is accurate because the keywords will be used to automatically identify the most suitable editor-in-charge for your submission. Requests for changing keywords after the submission has been completed will not be accepted.

After you have chosen the keywords, press the button "Submit" at the bottom of the page.

Please fill in the upload form with the following information:

• The complete list of authors (please use only plain text)
• The title
• The arXiv number (if any)
• The abstract

In "Enter the file to process" select the file (tex, tar.gz or zip) containing your contribution. If there is more than one .tex file you should also fill in the field "Master file name", for the system to know which file to compile.

On the same page you are also reminded of the keywords you have chosen and can assign a value to each keyword to establish its relevance for the paper. The default value is [100], meaning that all keywords will be considered equally relevant.

You can then click on "upload file". Please DO NOT double-click: push the upload button once, and please wait. The system will process your files. This can take about one minute or more depending on their size.

After completing the procedure, a submission report will be shown to you with the data of your contribution and the link where you can upload additional materials (the "upload file" button. For further infromation, see the section Supplementary material attached). If, on the other hand, the submission fails the report will inform you of the error(s) that have occurred. In particular if the (La)TeX compilation fails, please read the .log file, fix the error on your computer and try again. Should you be unable to solve the problem, do contact the Editorial Office.

Please make sure that after you have submitted your paper you go to "My author pages (corresponding author)" from the JHEP home page. Click on the appropriate preprint number and scroll down the page. Please check all available data on your submission. Should you need to communicate with the editor or the editorial office, you will find the appropriate e-mail tool. You will be able to communicate with the editor-in-charge in this way at every stage of the editorial procedure.

Revised versions can be submitted only if requested by the editor, contributions must therefore be originally submitted in their final form.

Once accepted, major revisions will be labelled as "revised".

The revisions requested by the editor are listed in your author's page in "State of preprints" in the sections "To be revised (major revision)" and "To be revised (minor revision)" respectively.

Authors who have been asked to revise their preprints must attend to the requested modifications and provide a new version of their preprints within 90 days at most in case of major revision, 30 days in case of minor revision. If the revised version is not submitted by the deadline the original submission will be withdrawn and any revised version will have to be considered as a new submission.

The revised preprints must be uploaded from the preprint page by clicking "submit revision" or "submit minor revision". You can resubmit via the arXiv or by web upload.

The cover letter with your reply to the referee report is mandatory and should clearly describe all the changes with respect to the previous version, explaining whether or not you have addressed the editor's requests. You will be asked to enter the cover letter in a text area during the upload procedure. Please make sure you save it in a file on your computer before uploading it, as a network failure could cause the resubmission to fail and the cover letter might get lost. Should you forget to enter the cover letter when resubmitting your paper, please connect to your JHEP Author pages and send it with the "write to editor" e-mail tool.

In case your cover letter needs to be written using LateX, in order to submit it please do the following:

1) connect to the preprint webpage and click on "submit revision"

2) in the text area for the cover letter write "the cover letter has been attached to the preprint as a pdf file"

3) complete the submission process

4) upload the pdf file of your cover letter using the tool available for the supplementary material ("upload file" button at the bottom of the page confirming the successful upload of your revised preprint).

Contributions are selected, processed and reviewed as fairly as possible, with no discrimination, by active scientists in the field. Authors of contributions that have been rejected can appeal and reply to the editor and referee(s). Appeals must be scientifically justified and not polemic. Please send your rebuttal letters by connecting to the preprint page and using the "write to Editorial Office" button. Second appeals are not considered unless there is a clear history of unfair treatment of the manuscript.

Although the identity of editors is anonymous, authors can communicate at all times with them through the appropriate "write to editor" button on their pages, or through the Editorial Office.

Errata and addenda can be submitted to JHEP as stand-alone articles following the instructions below.
1) Click on "submit an erratum" or "submit an addendum" in JHEP and see the list of published articles with you as corresponding author.
2) Find the article in question and click on "submit erratum" or "submit addendum".
3) Continue the submission process (see instructions).

The file submitted should be as follows.

File format - LaTeX and pdfLaTeX
Title - "Erratum: Title of the original paper" or "Addendum: Title of the original paper". Different titles will be corrected during the typesetting stage.
Abstract - it is the author's choice whether to include it or not in the file. In any case, abstracts will not be displayed on the published erratum/addendum's web page.
Keywords - They must not be included.
References - References to specific parts of the original article (equations, figures, tables, etc.) must be consistent with the numbering of its published version.

Please refer to the section File preparation if you need to submit an archive.

Errata and addenda are the only way to modify articles after publication. They are peer-reviewed, typeset and proofread before publication.

A preprint can be withdrawn at any moment during the review process, by clicking on the appropriate button.

A coauthor is a registered user selected by the corresponding author that has access to the author pages without being able to view the correspondence relating to the paper or change the status of the paper.

Select Coauthors

After you have submitted your paper it is possible to select coauthors for your paper. From the JHEP home page select the "my Author pages (corresponding author)" and click on the appropriate preprint number. At the bottom of the page you will find the "Select Coauthor" button which allows you to select and notify the coauthors of the paper.

Please note that in order to be selected as a coauthor the person must already be a registered JHEP user.
The information regarding registrations are available in the section General.

Switch Corresponding Author

Once a coauthor has been selected it is also possible to change the corresponding author to one of the coauthors using the "Switch Corresponding Author" button.

With this operation, the existing corresponding author becomes a coauthor and the selected coauthor becomes the new corresponding author.

As soon as a new contribution is submitted to JHEP, a preprint number is assigned and the preprint appears in the section "Waiting for Editor's decision". The preprint number identifies your contribution throughout the editorial procedure, and is required for any correspondence with the JHEP Editorial Office.

Figure 1. The preprint number

To access the preprint web page of a particular document:

1. Login to the JHEP website at SISSA (http://jhep.sissa.it)
2. Click on "my Author pages"
3. The preprints still in progress are in the "pending papers" page divided into sections according to their status.

The preprint web page for a particular preprint contains all the information about that preprint, except for confidential data (i.e., editor and referee names). The main actions that you can perform from the preprint web page are the following:

• check the status of the preprint and the progress of the editorial procedure
• download the preprint in the PDF format
• communicate with the Editor and the Editorial Office
• read and download the report
• submit the revised version of the preprint, if requested by the editor.

After your contribution has been accepted for publication in JHEP, you are required to accept the Copyright Agreement and the Open Access Conditions (see section Copyright statement). After you have done so, your contribition is typeset and sent back to you for proof-reading. At this stage you can

• view the typeset version of your document in PDF format
• proof-read the document for mistakes or minor changes before publication. The only corrections acceptable at this stage are the following:
  • layout (i.e., wrong floating of figures or tables),
  • spelling mistakes in words or formulae,
  • wrong cross-references among formulae and text,
  • mistakes or updating in references
• The corrections must be requested using the web form accessible with the button "send proofs", explaining where they occur in the document (page number, paragraph and line, or equation number) and specifying both the old (wrong) version and the correction.
  Please notice that if the corrections you request are not minor, the paper will be shown to the editor-in-charge for approval. If (s)he reckons that they affect the content significantly, you may be requested to submit a revised version of the preprint for which a new review process will begin. This will be listed in the "Pending revision after proofreading" section.
• 
  
• approve the document for publication (unless there is a request for information from the editorial office).

When you approve the document for publication, or after your requested corrections have been implemented, the document is sent for publication on the Springer website. Please note that if there is no feedback from the authors within 7 days from the first proof-reading notification, the document is considered suitable for publication as it stands. It will be stored in the "published" section of your JHEP author pages and will also be available on the Springer website.

At the time of publication, the paper will receive a definitive paper number (fig. 2).

Figure 2. Definitive paper number

After an article has been accepted for publication, authors are requested to accept the Copyright Agreement and the Open Access Conditions available here (link).

Only after the above agreement and conditions have been accepted, will the article be typeset and sent back to the authors for proofreading. Delays in the acceptance of the copyright agreement will inevitably cause delays in the production and publication of the article.

In case the copyright agreement is rejected, the article will be archived and will not be published in JHEP.

Papers published in JHEP are available from the Springer website.
Authors can access all versions of their JHEP papers at jhep.sissa.it  --> "my Author pages" --> "Published". Regrettably, source files for the typeset and published version cannot be provided.
