The Fourth International Workshop on Future High Energy Circular Colliders

12 Sep 2014, 08:00 → 13 Sep 2014, 18:00 Asia/Shanghai

Haijun Yang (Shanghai Jiao Tong University) , Xinchou Lou (IHEP, Beijing)

The workshop is dedicated to bring together people interested in circular high energy e+e- collider (CEPC) as a Higgs factory as well as a future circular high energy pp collider (SPPC) beyond the Higgs factory. Participants will report on the progresses made in theory, accelerator design, detector design and optimization, simulations of benchmark physics processes etc. since the CEPC-SPPC kick-off meeting in September 2013. The focus will be on the preparation for the CEPC pre-CDR. International collaboration and study organization will also be examined.

There are three CEPC working groups. If you would like to give a presentation at the CEPC workshop, please contact related group conveners listed in the following.

- Accelerator Working Group: Qing Qin (qinq@ihep.ac.cn) and Jie Gao (gaoj@ihep.ac.cn)
- Theory Working Group: Hongjian He (hjhe@mail.tsinghua.edu.cn) and Shouhua Zhu (shzhu@pku.edu.cn)
- Physics & Detector Working Group: Yuanning Gao (gaoyn@mail.tsinghua.edu.cn) and Shan Jin (jins@ihep.ac.cn)

The workshop will be held at Shanghai Jiao Tong University (Minhang Campus) on September 12-13, 2014. Detailed information about the workshop including visa, accommodation and ground transportation etc. is also available.
