Description

The 2025 European Edition of the International Workshop on the Circular Electron-Positron Collider (CEPC) will take place in Barcelona, Spain, June 16th to 19th.

CEPC poster 25

The workshop aims at gathering scientists from Europe and around the world to pursue international collaborations for the study of the physics potentials of the CEPC and accelerator and detector optimization, deepen R&D work on critical technologies for future machines and experiments, and develop plans towards an Engineering Design Report (EDR) for the CEPC accelerator and a Technical Design Report (TDR) for a reference detector. 

The workshop program consists of plenary sessions and parallel sessions. They will cover: Physics, Accelerator, Detectors, Computing, Tools and Performance developments relevant for the future colliders.The workshop encourages participation from early career scientists, especially from post-graduate students and postdocs.
