The 1st CEPC Physics Workshop toward Physics Whitepaper and TDR

1 Jul 2019, 08:00 → 5 Jul 2019, 18:00 Asia/Shanghai

PKU CHEP

The Circular Electron Positron Collider (CEPC) is a future Large Scale Collider facilites. Installed in a 100 km tunnel, the CEPC could produce 1 Million Higgs bosons, 100 Million W bosons, and nearly 1 trillion Z bosons in 10 years' operation. The prior physics motivation of CEPC is to serve as a precise Higgs factory, meanwhile, it also has a huge physics potential on the EW, QCD, Flavor physics and new physics hunting. To profound understand the physics potential at the CEPC, and to address the critical technical requirements (theoretical uncertainty control, interpretation, combination, etc). This workshop serves as a forum to discuss all those critical questions and looking forward to your active participation.
