CEPC Physics and detector plenary meeting
Wednesday, December 12, 2018 from 15:00 to 18:40 (Asia/Shanghai)
at IHEP ( A415 )
Attending: Joao Guimaraes da Costa, Gang Li, Huirong Qi, Zian Zhu, Yaquan Fang, Jianming Qian, Zhaoru Zhang

1. Joao firstly mentioned the news for the coming conference in 2019.
Hong Kong Program, January 2019
Calorimeter Workshop, Beijing, March 2019
CEPC Workshop European Edition 2019, Oxford, April 15-17, 2019
2019 International Workshop on CEPC, Beijing, November 18-20
2. Then he summarized the review comments for detector from IAC and CDR international review.
The IAC suggested to re-organize structure to include international colleagues in the leadership structure, and make a plan for a detector progress report (Pre-TDR). The work should focus on detector R&D and try to attract international participation to these activities. Very importantly we should form a Detector R&D Committee with international participation that can evaluate R&D proposals and be used to support funding requests from foreign partners. Franco mentioned that Italy will be submitting proposals in July and results will be known by September. It would be nice to get this committee operational such that they can provide an opinion before September. Franco also suggested that the Internationalization of the IB should happen at the same timescale.
Franco asked if co-funding from China would be possible for foreign proposals. This is difficult and needs to be discussed outside this meeting.
The CDR international review committee suggested to expand the physics topics to tt-bar threshold (also the IAC), flavor physics, and QCD physics. New physics topics and further Higgs measurements should also be pursued.
The committees recommend an extended MC simulation framework to be shared. Franco mentioned that FCC-ee folks are starting to establish a MC simulation framework and common efforts should be explored.
The committes also adivse to develop common detector operation strategies, and study the detector operability at the highest luminosities possible at the Z-pole. For instance, a common power management structure taking into account the specificity of CEPC, should be considered.
3. Based the these comments, the most important and urgent thing is to re-organize the Physics and Detector Working Group. Joao proposed a new structure of the group which classify the sub detector to silicon tracker, gas detector, calorimeter, MDI, Magnet and Muon, and establish the common groups of detector simulation and software, trigger and DAQ and service and integration, then the physics analysis group being as the performance check and physics research. It was proposed that the Muon group be intergrated into the gas detectors group.
For each sub-group, we need to seek international nominations to realize one international convener for each sub group. We also need meetings for subgroups regularly
Franco point out that the particle ID study should be involved and can be a cross group to serve all the sub-groups.
Joao asked whether we need sub-sub groups. Franco thought it is no need because we need maximum mixture of the communication and cooperation among every detectors to be as integration.
Jianming suggested to establish a tracking group as the merge of silicon trackers and gas detector, although others felt this was too broad since the aim is R&D. The overal tracking optimization is however an issue and it needs to be handled globally. This also pertains to the full detector optimization.
At last, people discussed the time scale for establishing the group. Joao suggested to collect nominations for subgroups leadership for about one month, and start new organization in February. Further discussion will happen at the steering committee meeting.
