Types of LHCHWG documents

(Concerning the actual preparation of the documents, see here.)

LHCHWG Report types can be any of the following:

(a) LHCHWG Internal Note: This could be used for internal work reviews or work plans. For example, communications that often occur by private conversation (email) between experiment and theory should be documented in the form of Internal Notes (e.g., cross section numbers, scale recommendations, etc.). This facilitates future checks and better handling of the information. Internal Notes are not required to have the format of a formal article, but are meant as informal reports on the discussion. They are signed by the (most likely few) individuals who have done the work.

The authors of the note submit a draft to the conveners of the appropriate WG who will review the document and, after approval, create a CDS entry for it. This automatically assigns a report number of the form LHCHWG-INT-20XX-XXX to it. The WG conveners also create an entry on the LHCHWG Library page, and subsequently inform the SC about it.

Internal Notes are not intended to be published beyond that. In particular, submission of Internal Notes to the arXiv is strongly discouraged. However, Internal Notes can be used as an intermediate step towards the release of an Official Report. Once the CDS comments on the Internal Note are taken care of by the authors, the WG conveners may create a new CDS entry for the document, classifying it as an Official Report. In this way the CDS comments and iterations will not appear on the final CDS approved version of the document. The subsequent procedure follows that for an Official Report.

(b) LHCHWG Official Report: This could be used for (interim) recommendations which can be cited by collaborations in papers and proceedings/reports representing the LHCHWG. Official reports are developed within the corresponding WG in coordination with the WG conveners. These reports can, but are not required to, be started from an existing Internal Note. When the report is ready for review, the authors ask the WG conveners to post the report on the CERN CDS system for comments, inform the SC via email, and send an email initiating review by the corresponding WG during a period fixed by the WG conveners. Submission to CDS automatically generates the LHCHWG-20XX-XXX report number. Once this review is complete, the WG conveners send a request to the SC, which is responsible for the final sign-off. The SC sends an email to invite all members of the LHCHWG to comment via the CDS system during a period fixed by the SC and adjusted to the complexity of the content and length of the report. Everyone who has substantially contributed to the work and to the discussion, according to the judgement of the WG conveners and the authors, is invited to sign the report. Once all comments have been addressed, the SC approves the document.

The approved report should display the report number and include the endorsement “work done on behalf of the LHCHWG”. Official reports can be submitted to the arXiv. The documents submitted to the arXiv and CDS should both coincide with the version endorsed by the LHCHWG. If any part of the work presented in the report or otherwise developed within the LHCHWG is included in a journal publication, an acknowledgments section should refer to the work performed within the LHCHWG.

(c) LHCHWG CERN Reports: These are special official reports made of a compilation of all works done in the group. Compilation and review of the different sections will be handled by the WG conveners, and final review will be performed by the SC. Report numbers are of the form CERN-20xx-00x. The report will be signed by all members of the LHCHWG who contributed. LHCHWG CERN reports will be submitted to the arXiv.

We encourage ATLAS/CMS to rely on and cite only official and CERN reports. If they want to use results from internal notes, they should contact the WG conveners. They can then make a call inside the WG for initiating the process for the transmutation of an internal note to an official report.

Starting a new note and GitLab repository

When you are ready to start a new note, contact the relevant sub-group conveners and the Steering Committee members. They will create a temporary directory for you in GitLab. If the topic of the note spans across several sub-groups, the Steering Committee will help to coordinate. Once the note takes shape, the Steering Committee will assign a note number (e.g. LHCHWG-INT-XXXX-XXX) and the directory will be renamed accordingly. We have to make sure that all notes are placed under GitLab system with each directory for both INT note (e.g. LHCHWG-INT-2025-001) and official reports (e.g. LHCHWG-2025-001). Current directories on GitLab for LHCHWG notes are:

a) Internal notes: https://gitlab.cern.ch/LHCHIGGSXS/InternalNotes

b) Official Reports: https://gitlab.cern.ch/LHCHIGGSXS/Notes

c) CERN Reports: https://gitlab.cern.ch/LHCHIGGSXS/YellowReports

All LHCHWG documents should be uploaded to the GitLab system under the appropriate (above mentioned) directories.

- A general introduction to the use of GitLab can be found at https://guides.github.com/introduction/git-handbook/

Publishing LHCHWG public material to SciPost "Physics Community Reports"

To improve the recognition of work done within the LHCHWG, a new branch of SciPost called "Physics Community Reports" has been created. Physics Community Reports is intended to be a place where work that often does not reach the threshold for a publication in a typical journal but still provides important information (e.g. updates of cross-section predictions) can be published. We intend to submit our public notes and yellow reports to this new branch once the internal review is finalized. Refereeing criteria are adapted to the purpose, at least one of the following should be fulfilled (in addition to the general acceptance criteria):

• Provide a novel and synergetic link between different research areas.
• Present a step forward on a previously identified research stumbling block.
• Fill in a gap concerning reference results or benchmarks in a particular research direction, with clear potential for multi-pronged follow-up work.

Further information is available at this link: SciPost "Physics Community Reports".
