ESPPU draft of UK input

Monday 17 Feb 2025, 08:00 → 18:00 Europe/London

This page is being used to share and collect comments on draft(s) of the UK's national input to the 2026 European Strategy for Particle Physics Update (ESPPU). 

The timelines for this process are outlined below:

• 17th February - 3rd March: first circulation of draft of UK input around the community, with invitation to provide feedback/comments.
• 3rd-14th March: the drafting team will work to implement comments.
• 14th-21st March: circulation of final draft around the community. We hope that comments received at this stage would be mainly clarification/editorial points.
• 31st March: first deadline for submission of national inputs.
• 28th April: community drafting day at RAL: https://indico.stfc.ac.uk/event/1430/ (registration now open). This discuss updates to the draft following the community submissions at the end of March, and the prioritisation of alternative future collider options at CERN and non-collider experiments (which are not being provided in the first draft of the input).
• 26th May: deadline for updates to the national input ahead of the open symposium.
• 23-27 June: Open symposium in Venice https://agenda.infn.it/event/44943/overview (registration now open).

08:01 → 08:02 Version 2 of the UK's national input draft: circulated 14th March

Following the first round of community comments, efforts have been made to implement as many comments as possible, and ensure that we reflect the discussions at the drafting meetings. We propose to post replies to all comments in the google doc for draft 1 in the w/c 17th March and a list of major changes to the draft can already be found in the google doc.

We hope that the circulated draft is close to final, and that remaining comments will be mostly grammatical/editorial. If there are points the community feels are missing from the draft (beyond the points already noted in the draft) we can add them to the agenda for discussion on 28th April. Once the comments have been received on this draft a final draft will be prepared for submission ahead of 31st March.

Comments should be provided as written comments in the google-doc linked. Please provide your name and relevant line numbers/section numbers in the PDF. The deadline for comments is 6pm (UK time) on Friday 21st March, after which the document will be made read-only.

Please do not send comments by email.

08:02 → 08:03 Version 3: circulated 28th March and to be submitted 31st March (noon)

Following the second circulation, the drafting team has implemented as many comments as possible, trying to remain consistent with the sentiments/discussion in the drafting meeting and also avoiding significant changes in messaging.

The new draft will be submitted to the ESPPU process around noon on Monday 31st March. At this point we are not accepting further detailed comments however:
- If you see any typos please email Sarah, Jim, Ruben, Davide and Mark and we will attempt to fix them before the deadline.
- If there are points you'd like to raise for discussion in the next drafting meeting on April 28th please add them to the google doc.
