Description
Welcome to the 9th FCC Physics workshop in Munich-Garching, Max Planck Institute for Physics!
The workshop will take place from Monday January 26 to 
Friday January 30, 2026. On Monday morning, an Early Career Researcher session will complement the program. The FCC dedicated sessions will start on Monday at 14:00 and will and on Friday at 14:00 after a common lunch.
Conference fee includes 5 lunches and 2 dinners.
We plan to hold a poster session during on Monday evening together with a Welcome Bavarian reception. Participants are invited to submit their proposal for a poster using the "Call for Posters" link on the menu.
If you want to remain up-to-date on the FCC physics and experiments activities, please register to the following mailing list.

Presentation of FCC ECP document draft
The FCC ECF document summarizes the findings from the 4th session held during the FCC Week 2025. In contains the views expressed by early-career professionals on how to shape a future career within a next-generation large-scale experiment. While this was asked in the frame of FCC many points (such as sustainability, how to communicate to the public and common concerns) apply to many early-professionals across different fields and domains
