The 2021 International Workshop on the High Energy Circular Electron Positron Collider

8 Nov 2021, 08:00 → 12 Nov 2021, 18:55 Asia/Shanghai

Jianchun Wang (IHEP) , Shan Jin (ihep)

The 2021 international workshop on the high energy Circular Electron-Positron Collider (CEPC) will take place between November 8-12, 2021 at the Nanjing Grand Hotel, hosted by the Nanjing University. It will be held in online mode only, using zoom.

The workshop intends to gather scientists around the world to study the physics potentials of the CEPC, pursue international collaborations for accelerator and detector optimization, deepen R&D work of critical technologies, and develop initial plans towards Technical Design Reports (TDR). The high energy Super proton-proton Collider (SppC), a possible upgrade of the CEPC, will also be discussed. Furthermore, industrial partnership for technology R&Ds and industrialization preparation of CEPC-SppC will be explored.

The workshop presentations are by invitation only. If participants are interested in presenting, please contact the conveners of the corresponding session.

The session time table and clickable zoom links can be found in the PDF file.
