10:00 → 10:10 Status

Speaker: Kang Yu (TDLI, SJTU)

1. Learn about weak interaction, understand electroweak unification, Higgs mechanism and CP violation in K0 meson in a general way.
2. Review the path integral formulation of coherent state.

10:10 → 10:20 Status

Speaker: Linjing Duan (TDLI, SJTU)

Zvvy nTGC

• Write the script to test the fitting program, fitting is ongoing 
• Try to get some results for the 1D operators by this week, then move on to 2D

10:20 → 10:30 Status

Speaker: Jun Wei Lok (TDLI, SJTU)

the breakdown voltage of SiPM under 30C (38.546V)

data of 20C and 10C have taken

-30, -20, and 0C experiment should be conduct to obtain more accurate Temperature coefficient


 

10:30 → 10:40 Status

Speaker: Zelin Yan (TDLI, SJTU)

Hyyd analysis:

• add mc23e signal samples & update the obs(expected) limit to 0.8%(0.9%)

H2a4b analysis: 

• add 0b region(Z+jets CR) into TRExFitter config

HGTD upgrade: 

• setup quasar opcua servers to monitor(from Alex)
• update the monitoring code 
• wafer test 

Future plans:

• Hyyd analysis:
  • correlate the run3 ggF channel theoretical systematics with others and qualify the effect 
  • run the ranking plot 
• HGTD upgrade: 
  • learn how to use the quasar framework
  • wafer test in Hualing(From Hancen, ihep)
