UK ESPPU drafting meeting

Monday 4 Nov 2024, 09:00 → 17:15 Europe/London

Jim Clarke (STFC), Ruben Saakyan (UCL), Sarah Williams (University of Cambridge)

The first drafting day will take place at Daresbusy Laboratory (https://www.ukri.org/who-we-are/stfc/facilities/daresbury-laboratory/), and a zoom connection will be available to faciliate hybrid participation.

We aim to prepare the text for the UK’s national input for the ESPPU through a series of community drafting days. These will be open to all, and run in a hybrid manner. We hope that a lot of the drafting can be performed in ‘real-time’, following discussions of suggested sample statements prepared by the drafting team and in light of discussions of input provided by projects. Both the project inputs and the list of "sample statements" will be made available to the community (through the agenda) on Wednesday 30th October such that those unable to attend on 4th November can provide comments. Details on the information that will be requested from projects can be found in the slides here: https://docs.google.com/presentation/d/1BLL9ETCdwOfEcTebhsBLvjeMH4kkfYEd12Lrao-oJlQ/edit#slide=id.g305c503b623_0_59 

Following the first drafting day in November, an initial draft/summary of discussions will be circulated around the community for comments and to encourage further reflection ahead of the second drafting day in January.

The members of the drafting team are listed below. The role of the drafting team is to faciliate the drafting of the input, through preparing (a range of) draft statements to be discussed at the drafting day(s), and following up on suggestions/ comments in between meetings. The drafting team has representation across a range of experimental particle physics areas (collider and non-collider), particle physics theory, accelerator and detector R+D, software and computing and from the Early Career Researcher (ECR) community. Where possible members have been drawn from current PPAP membership, the UK delegates on plenary ECFA or selected after consultation with those leading efforts in the UK. The drafting team will be coordinated by Ruben Saakyan (chair of PPAP), Sarah Williams (UK delegate on plenary ECFA) and Jim Clarke (Director of ASTeC).

Drafting team: Julia Allen*, Daniela Bortoletto, Jim Clarke, Davide Costanzo, Patrick Dougan*, Sinead Farrington, Henning Flaecher, Joel Goldstein, Mark Lancaster, Atanu Modak*, Holly Pacey*, Chris Parkes, Haroon Rafique, Aidan Robson , Ruben Saakyan, Michael Spannowsky, Jessica Turner, Mark Williams, Sarah Williams, Matthew Wing (* ECR membership to be augmented with the new ECFA-ECR representatives upon changeover in January 2025)

The UK's national input will be organised around (but not necessarily limited to) the set of questions provide by the ESG (https://ecfa.web.cern.ch/ecfa-guidelines-inputs-national-hep-communities-european-strategy-particle-physics-0) which are also paste in the relevant sessions of the drafting day. The national input will be restricted to a 10-page limit for the main body of the text. Following the second drafting day, the draft will be compiled into a complete document  in February to be circulated to the community for comments and feedback. This will allow time for a second draft to be circulated to the community early/mid March to be submitted by the deadline on 31st March.

09:00 → 10:00 Project inputs

NOTE: THE DRAFTING DAY WILL NOT START UNTIL 11AM (COFFEE AVAILABLE FROM 10.30AM)- THIS BLOCK IS A PLACEHOLDER FOR UPLOADING THE INFORMATION THAT WILL BE SUBMITTED BY PROJECTS FOR THE DRAFTING DISCUSSIONS.

This part of the agenda will be used to upload the information that will be submitted by projects for consideration in the drafting discussions. Further detail on this input can be found here:

10:30 → 11:00 Coffee

11:00 → 13:00 Session 1

Overview of drafting plans and summaries of information submitted by the projects

11:00 Introduction/overview of the drafting process

Speaker: Dr Sarah Williams (University of Cambridge)

11:20 Physics landscape (summary of project submissions and projections) +discussion

Speaker: Sinead Farrington (University of Edinburgh)

12:00 Accelerator landscape (summary of project submissions, costs, environmental impact) + discussion

12:30 Discussion

13:00 → 13:45 Lunch

13:45 → 15:15 Session 2

Begin drafting discussions on the future collider landscape (question 3):

a) Which is the preferred next major/flagship collider project for CERN?
b) What are the most important elements in the response to 3a)?
i) Physics potential
ii) Long-term perspective
iii) Financial and human resources: requirements and effect on other projects
iv) Timing
v) Careers and training
vi) Sustainability
c) Should CERN/Europe proceed with the preferred option set out in 3a) or should alternative options be considered:
i) if Japan proceeds with the ILC in a timely way?
ii) if China proceeds with the CEPC on the announced timescale?
iii) if the US proceeds with a muon collider?
iv) if there are major new (unexpected) results from the HL-LHC or other HEP experiments?
d) Beyond the preferred option in 3a), what other accelerator R&D topics (e.g. highfield magnets, RF technology, alternative accelerators/colliders) should be pursued in parallel?
e) What is the prioritised list of alternative options if the preferred option set out in 3a) is not feasible (due to cost, timing, international developments, or for other reasons)?
f) What are the most important elements in the response to 3e)? (The set of considerations in 3b should be used).

15:15 → 15:45 Coffee

15:45 → 16:45 Session 3

Drafting on non-collider activities/priorities (at CERN)- i.e. question 4
a) What other areas of physics should be pursued, and with what relative priority?
b) What are the most important elements in the response to 4a)? (The set of considerations in 3b should be used).
c) To what extent should CERN participate in nuclear physics, astroparticle physics or other areas of science, while keeping in mind and adhering to the CERN Convention? Please use the current level and form of activity as the baseline for comparisons.

16:45 → 17:15 Session 4

Closeout and discussion of next steps
