10:00 → 10:10 Status

Speaker: Kang Yu (TDLI, SJTU)

1. I have put a lot of time into reviewing QFT, but I still get confused about applying the Feynman propagator to solve practical problems.
2. I feel like I'm below the average level in some of my courses and I'm trying to catch up.
3. Apart from (1)&(2), I haven't made any progress in the last week.

CEPC Zvvy nTGC

• we have all the signal (SM, Interference, Quadratics) and background Ntuples.
• Drawing the histograms of Photon PT and Missing E from every signal and background Ntuple. the code was tested successfully.
• An example is shown here: the Quadratics contribution of named Operators named BB

 

 

 

 

 

 

 

 

 

 

• Plan to do: prepare all the three terms of nine operators of nTGC and background histograms, for the fitting (to be finished by next week)
• Produce a signal-background comparison plot, similar to the one generated with Delphes in my undergraduate project. 
• the inclusive signal term will be(red curve) : SM + Interference + Quadratics

10:30 → 10:40 Status

Speaker: Zelin Yan (TDLI, SJTU)

H2a4b analysis:

• Create initial version TRExfitter config and test in 2b3j region

Hyyd analysis:

• Re-run the ranking plot 

HGTD upgrade:

• Take part in wafer test 
  • test new probecard
  • test automatic programming

Next： 

• H2a4b: 
  • Debug for the TRExfitter config 
• Hyyd:
  •  Get new 2023+2024 ws from Federica and re-do the combination
• HGTD upgrade:
  • Continue to wafer test and finish 5~6 new wafer 
  • Figure out how to monitor alignment by using  felix-io and felix-tohost

DarkSHINE ECAL electronics test

• precision evaluation under different sampling rate: to meet 10% @ min. signal and 2% @ max. signal, a sampling rate larger than 100MS/s is requirement

11:30 → 12:25 REU: Undergrad Research Discussions

11:30 Status

Speaker: Peixu Teng (SPA, SJTU)

Summary of the past few weeks：

1. learning QFT. 
2. try to use MadGraph5 and can produce some simple examples. But the function of each parameter during the generation process is still needed to remember.
3. Trying to recall some darkshine simulation operations

To be continued:

1.  I gauss QFT will occupy less time till next month
2.
