5th FCC / DRD France Workshop, Paris (Nov.26-28/2025)
Dear Colleagues,
The fifth FCC / DRD - France / Higgs & ElectroWeak Factory workshop will take place at APC and LPNHE in Paris, in an in-person mode. Zoom connection will nevertheless be available.
It will take place from Wednesday, November 26, 2025, 14:00 to Friday, November 28, 12:30. Wednesday afternoon and Friday morning it will be in APC (metro Bibliothèque Francois Mitterand), while Thursday it will be in amphi Charpak at LPNHE (metro Jussieu)
The workshop aims at reviewing the overall FCC status and the implications of the FCC French teams in the DRD collaborations, in order to strengthen the synergies, and intensify the French participation in the FCC pre-TDR phase. Studies on physics and the constraints that this physics entails on detectors, in particular the physics of FCC-ee, but also FCC-hh will be presented. Progress on Theory and on Accelerator for FCC will be reported. There will also be dedicated societal/environmental and ECR sessions
The agenda and the registration conditions are being finalized.
Registration will open on October 30th
Please get ready to join us in Paris !
