Joint Workshop of the CEPC Physics, Software and New Detector Concept

14 Apr 2021, 08:00 → 17 Apr 2021, 12:40 Asia/Shanghai

YangZhou

The Joint Workshop of the CEPC Physics, Software and New Detector Concept will take place on April 14-17, 2021 in Yangzhou, China (the registration starts from the afternoon of April 13th). The workshop is co-sponsored by Yangzhou University, Nanjing Normal University and IHEP. 

The Circular Electron Positron Collider (CEPC) aims at a future Large Scale Collider facility. 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 in the EW, QCD, Flavor physics and new physics hunting.

The purpose of the workshop is to further understand the physics potential at CEPC as well as the requirements on the detector. The physics discussions during the workshop will be dedicated to a CEPC physics white paper. The goal for the detector discussions are to plan for an innovative detector design for the CEPC, beyond those described in the CDR, and that will utilize new detector technologies and concepts.

We are looking forward to your active participation and expect to meet you in Yangzhou during “烟花三月".
