Welcome to the first issue of X Courier!

Influncex by the CERN Courier, we choose the courier as our bimonthly news summary of X-Team. The main goal is to report the progress has been made in the past and collect upcoming meetings and conferences. We hope the courier will sever as a growing dairy for our team and userful resources whenever possible.

Publications

• “Precision Higgs Physics at CEPC” was submitted to the Chinese Physics C. Congratulations to Maoqiang and Ryuta for your hard work on Higgs invisible and ZZ decay analysis!

• “Characterization of the first prototype CMOS pixel sensor developed for the CEPC vertex detector” was submitted to Radiation Detection Technology and Methods. Cogratulations to Ryuta for your contribution on develping the FPGA firmware to make the DAQ possible. Sorry that the paper could not list all the contributers, I would like to thank for Tao, Maoqiang, Hao, Yaoyao, Xiaoxu, Xudong, and Jason for your contributions!
