1 Status

Speaker: Zelin Yan (Wuhan Univ. & TDLI, SJTU)

2 Status

Speaker: Bai-Hong Zhou (TDLI, SJTU)

• Dark SHINE
  • Prepare the 4-GeV training samples;
  • Optimize the performance of GAN until June 30th;
• tri-Higgs
  • Talk with Nick to check the unknown branches;
  • Reproduce the Ntuples for the Signal-backgroud differentiation;

Production

• Biasing Study
  • Truth Trigger eff: rum samples (~2d)
  • Validation: check inclusive and estimate the Rate
• Update budget estimation
• Launch rare process production for electron samples

 

Positron Analysis:

• Tong found the cause of low reco efficiency in signal events: Acts only constructing tracks P >= 100 MeV
  • Fix (tune) Acts track finding parameters 
  • Could use nominal tracking instead of Acts until fix

 

Coorp with Yifan to work on seeding algorithm (until Jul.10)

8 Status

Speaker: Ngoc Khanh Vu (TDLI, SJTU)

9 Status

Speaker: Rui Yuan (TDLI, SJTU)

DarkSHINE:

HCAL scintillator: understood the issue(low event rate, calibration difference) and performance of the electronic readout. Calibration will be done soonish, to calculate ADCcounts/N.P.E instead of ADCcounts/mV->N.P.E

 

H2a4b: preparing H->2a sample (a is LLP);  preparation framework based on eastjet is on-going

 

Hzy/yy*: first look of spurious signal test using full lly Run3 bkg, it works, but so far no model can pass the test.

10 Status

Speaker: Tong Sun (TDLI, SJTU)

positron on target:

• calculate three signal efficiencies and get a preliminary limit for beam energy at 4 GeV.

others:

• investigate the issue about empty Acts_RecTrk_P and find that it is  the low energy (<100MeV) casusing Acts reconstruction failed.

PRP: Undergrad Research Discussions

11 Higgs as a probe to BSM phenomena

Speaker: Cai Qi (Zhiyuan, SJTU)

12 Dark SHINE

Speakers: Xiaobin Zhang (SPA, SJTU), yuming lin (SPA, SJTU)
