Contribution List

3. Introduction and aims of the meeting

Ruben Saakyan (UCL)

4/28/25, 11:00 AM

Introduction and digest of community inputs

4. News from Collider Physics inputs

Josh McFayden (University of Sussex)

4/28/25, 11:10 AM

Introduction and digest of community inputs

In this session, we aim to have 3 short "digests" of the various project submissions that will be available after the 31st March in the following 3 areas:
- Collider physics
- Non-collider physics
- Accelerator projects
For the two physics talks, the aim is not to try and perform the comparisons that will be performed by the Physics Preparatory Group ahead of the open symposium in Venice,...

9. News from Non-Collider Physics inputs

5. Updated discussions on 3c

4/28/25, 12:10 PM

Session 1: FCC strategy in global context. Scenario planing.

Discuss specific answers to 3 of the 4 scenarios listed:

1. If Japan proceeds with the ILC in a timely way?
   (2. If China proceeds with the CEPC on the announced timescale?)
2. If the US proceeds with a muon collider?
3. If there are major new (unexpected) results from the HL-LHC or other HEP experiments?

(2) will be discussed as part of the 3e discussions

6. Initial discussion on scenarios for consideration in 3e

4/28/25, 12:45 PM

Session 1: FCC strategy in global context. Scenario planing.

The following scenarios will be considered separately

1. [Cost/technical/environmentally unfeasibility]- FCC is unaffordable or unfeasible on either cost or environmental grounds.
2. [International developments] - CEPC is realised.
3. [Timing]- Timescales for FCC are pushed back.

7. Prioritisation of alternative "plan B" scenarios

4/28/25, 1:45 PM
