6th FCC France Workshop with International Partners

25 nov. 2026, 13:00 → 27 nov. 2026, 14:00 Europe/Paris

Dear Colleagues,

The sixth FCC - France and International Patrners workshop will take place at CPPM  in Marseille, in an in-person mode. Zoom connection will nevertheless be available to follow the sessions for those who cannot be on site, but not for presentations.

It will take place from Wednesday, November 25, 2026, 14:00 to Friday, November 27, 13:00 on the Luminy campus, at CPPM and a neighboring building, l'hexagone

Following the selection of FCC-ee as prefered future project by the CERN Council, and the beginning of the FCC-ee Reference Design Phase (RDP), the workshop aims at reviewing the overall FCC status and the implications of the FCC French teams, in order to strengthen the synergies, and intensify the  French participation in the FCC RDP. Studies on physics and the constraints that this physics entails on detectors will be presented. Progress  on Theory and on Accelerator for FCC will  be reported. There will also be dedicated Communication and Early Career Researchers sessions. 

The preliminary agenda visible on this site is close to being finalized.  

Please register and join us in Marseille !
