Second US Muon Collider Collaboration Meeting

Aug 7, 2025, 1:30 AM → Aug 8, 2025, 11:30 PM America/Chicago

University of Chicago

Karri Folan Di Petrillo (University of Chicago)

WELCOME TO THE SECOND ANNUAL US MUON COLLIDER COLLABORATION MEETING We invite you to the second meeting of the US Muon Collider community on August 7-8th at the University of Chicago. This will be an open meeting with the primary goal to engage broader participation in the muon collider effort, familiarize groups with the current status of physics, accelerator and detector developments, and discuss ways they can contribute to the effort. The main audience for the meeting are US-based physicists interested in working towards a Muon Collider as well as the physics it could cover, but all are welcome. Members of the leadership of International Muon Collider Collaboration (IMCC) will present the status from Europe, including the European Strategy process.  The meeting will begin on Thursday August 7th and include a banquet dinner that evening. We are also planning for a poster session and will open the call for abstracts shortly. The deadline for registration is 1 July 2025. Please note the Muon Collider Accelerator School taking place earlier in the week
