1. IAC recommondation
Joao firstly went through IAC recommendations and our respones and next step plans according to each recommendations.
Then discussed preparations for next IDRC meeting which is expected to be held in March. We need to finalize documents to be submitted to committee before Jan 15th. And people discussed where to put all the documents together.
2. SUSY Search at the CEPC
A preliminary SUSY sensitivity study has been performed to direct stau / smuon production and chargino pair production (Bino LSP and Higgsino LSP) in CEPC, which is promising. With assuming 10% systematic uncertainty:
For direct stau / smuon production, the discovery sensitivity reaches 115 GeV in stau / smuon mass.
For chargino pair production (Bino LSP), the discovery sensitivity reaches the phase space.
For chargino pair production (Higgsino LSP), the discovery sensitivity reaches up all the mass phase space except a corner at high ?? region.
Internal note and paper draft is ongoing.
