Future US Colliders Workshop

18 Jan 2022, 08:40 → 21 Jan 2022, 18:00 America/Los_Angeles

Caterina Vernieri (SLAC), Emilio Nanni (SLAC), Isobel Ojalvo (Princeton University)

The aim of this workshop is to gather together a number of theoretical, experimental and accelerator physicists to discuss possible future US facilities. In particular, we would like to review the linear e+e- collider (C^3) and future R&D directions for high energy machines: muon collider, gamma-gamma, e+e-, PWFA.

We would like to produce a short document as a summary of the workshop discussions that could be used as an input to the Snowmass process.

Snowmass Agora #2 on Future Colliders: Circular e+e- Colliders will held on 19 January, 2022. Please register for the event to receive the ZOOM link to attend. The registration will be open throughout the event.

In the context of the Snowmass 2021 Community Planning Exercise, the Accelerator and Energy Frontiers are pleased to announce a series of events, intended for all Snowmass participants, to critically discuss physics and technical aspects of different HEP collider concepts.

The events will be hosted by the Future Colliders initiative at Fermilab. The plan is to discuss both near and far future collider proposals, in different stages of development, synergistically grouped into five categories:

Linear e+e- colliders 
Circular e+e- colliders 
Muon colliders 
Circular pp and ep 
Advanced colliders

The events will take place once a month from December 2021 till April 2022, on Wednesdays 3-5 p.m. CST. The detailed agenda will be announced soon. We request you to please save the following dates:

Dec. 15, 2021
Jan. 19, 2022
Feb. 16, 2022
Mar. 16, 2022
Apr. 13, 2022

A "Collider discussion’’ will be further organized during the Energy Frontier Meeting planned for the week of March 28.

These events are meant to be focused critical discussions of classes of colliders that share similar concepts, and will have to specifically address both physics and feasibility considering aspects such as:

physics reach
challenges and R&D required
synergy of project with global context (comparative dis/advantages)
synergy of project with local resources  
time frame (short-term R&D, long-term construction)
Costs projections: both R&D and construction costs

Each event will consist of a set of brief presentations followed by a discussion session led by assigned moderators to encourage audience participation.

A summary of the discussion and highlights will be documented as a short report on this series, which will feed into Snowmass contributed papers by EF and AF.

With best regards,
