Rundgespräch: Theory Hub for Future Circular Collider e+e- Physics

2 Jul 2026, 13:00 → 3 Jul 2026, 16:00 Europe/Berlin

Ground floor meeting room (Helmholtz Institute Mainz)

Christophe Grojean, Felix Yu (Johannes Gutenberg University, Mainz), Giulia Zanderighi (CERN&Oxford), Tilman Plehn (Heidelberg University)

We will host a round-table discussion for the preparation of a DFG Priority Programme submission to establish a "Theory Hub for Future Circular Collider e+e- Physics" at the Helmholtz Institute Mainz on the Johannes Gutenberg-University, Mainz campus.  This event is financially supported by the DFG and is open to all theorists in Germany interested in FCCee physics who would submit an application for funding within the envisioned Priority Programme framework.

Registrations are moderated.  Accepted participants will have travel and accommodation expenses reimbursed directly by the DFG.  Please be aware that hotel block reservations were released on June 12.  The registration deadline is June 24.

The Zoom link for the meeting is https://uni-mainz-de.zoom.us/j/67046345626?pwd=PdJ8AY7EdbI6mWbbebavVXwU0dzbDN.1 .

We have set up a Google Form to collect community input on "seed ideas" that would be funded via the successful SPP.  You can find the form here https://forms.gle/EW297hzLSdUawG896 .  Please submit your "seed idea" contribution by August 5, 2026.
