CEPC Physics and detector regular meeting
Wednesday, October 25, 2017 from 15:00 to 17:00 (Asia/Shanghai)
at IHEP ( A415 )
Attending: Joao, Franco Bedeschi, Gang Li, Haijun Yang, Hongbo Zhu, Liang Li, Meng Wang, Huirong Qi, Yunpeng Lu, Yaquan Fang, Zhijun Liang, Xiongfei Wang, Xuyang Liu
1. Introduction from Joao
Joao firstly go through the timetable for November workshop. Most of the talks have been fixed. For gas detector parallel session, the LCTPC may be canceled because we can't find the proper speaker. For Dual readout talk by Tianchi, he decided to change talk to new concept in calorimeter, everyone agree with the change.
For the Poster session, we decide to move some talks to poster session, which have already submitted the abstract but lost the chance for presentation at last. Then each group has several poster:
Vertex 1~2
Silicon 1
physics 2 And electroweak +1
TPC 4
DR 1~2
Magnet 4
Muon 1
MDI 2: one for background study and one for lumical
2. CDR discussion
Now Tianchi is the general editer for reviewing the text and rewriting things, in order to improve the text. Joao asked the CDR status and update for each group:
Chapter 3 is still empty, people should mainly work on it in the following weeks.
Silicon tracker: Meng said that they rewrite d some contents and remain others same with pre-CDR. He confused about the current structure for vertex, silicon tracker and TPC, since there is some common issues and correlation among these chapters, it's hard to arrange the chapter structure. But people agree that we can discuss it later, because the most important thing is adding more contents for this chapter.
TPC: they received the comments from Tianchi and modified the contents, also add the collaboration part.
Calorimeter: They add some sub-session into CDR, and most of the contents is finished until now. They will have a final version in git on next Wednesday.
Magnet: They modified the layout of figures in CDR and continue reviewing the text.
Muon: 3 session are added in this week, and the chapter related to SPPC, RPC option will be finished on next week.
MDI: They focus on producing the plots for CDR. Lumical updated a new shorter version in 2 pages. And Joao ask for the help to MDI group for Chapter 3, as it has strong relation with MDI, radiation expectation etc. Hongbo said they will prepare some text + number from MDI in one page, focusing on radiation part.
Physics: Gang unified the format of plots for this week. Joao suggested every groups use same Marco for the plots. Gang has already send the Marco to everyone. Also physics group should figure out the highlight measurement as the benchmark, and they will get a result on next week.
For Yuquan side, they merged some channels' results for Higgs analysis. They will have a draft before workshop. Also they are responsible for chapter 2, the results from EWK analysis should also be mentioned in CDR.
To compare the difference between CEPC_v1 and v4, also the difference between 3.5/3 T magnet filed. Physics group should do the validation before next Wednesday.
3. Mini-review preparation
It is a informal review, but Joao requires every group prepare a PDF file for their chapter and 10 minutes talk focusing on the highlight for chapter.
There are minutes attached to this event.
Show them.
