Cover page (1 page)
Each document submitted should carry a single cover page containing no more than the title, the contact person(s) and an abstract.
Comprehensive summary (maximum 10 pages)
The submitted document must be no more than 10 pages long (excluding the cover page and references) and must provide a comprehensive and self-contained summary of the input. It should address:
- scientific context,
- objectives,
- methodology,
- readiness and expected challenges,
- timeline,
- construction and operational costs (if applicable).
Back-up document
Additional information and details can be submitted in a separate back-up document, which can be consulted by the Physics Preparatory Group (PPG) if clarification on any aspects is required. But the back-up document is not a mandatory component of the submission.
Format and deadline for submission
The cover page and the comprehensive summary are to be submitted in portable document format (pdf) by 31 March 2025. The back-up document should have a cover page with the same title and contact persons and with the words “Back-up Document” added.

Please copy the abstract of your input into the field labelled “Content”. Please also indicate one or more submission themes (tracks) to which your input relates:
- Physics streams, matched to the PPG physics groups
- Electroweak physics incl. Higgs
- Strong Interactions
- Flavour physics
- BSM physics
- Neutrinos and cosmic messengers
- Dark matter and dark sector - Technology streams, matched to the PPG groups
- Accelerator technologies
- Detector instrumentation
- Computing - Additional streams mapped to ESG working groups
- Input from the National HEP communities and National Laboratories
- Projects and large experiments
- Communication, Education, Outreach, Knowledge and Technology transfer, Career issues
- Sustainability
- Others (e.g. personal contributions)
Distribution
All the documents submitted will be forwarded to the PPG and the European Strategy Group (ESG), and will be made public after the submission deadline. Addenda that the authors wish to keep confidential (i.e. seen by the PPG and ESG only) should be sent by email to espp2026.input@cern.ch.
Please note that Indico always refers to submitted documents as "abstracts".
