4 Status¶

Speaker: Xuliang Zhu (TDLI, SJTU)

Todo:

• Update DarkSHINE plot style (ticks, scatter plot style, ratio plot overlay example, color sequence)
• e+/e- PN ECAL sample size/time optimization
• Positron XGBoost: 
  • sample preparation by chunk
  • dummy sample test
  •

6 Status¶

Speaker: Danning Liu (TDLI, SJTU)

Hy*y : 

Fixed the issue when merging JO to cvfms by reproducing tarball files, reducing event numbers for per job, and validated locally. 

CEPC nTGC: 

Generated validation samples for fast simulation 

Ready to use Delphes for fast simulation and validate with full simulation 

7 Status¶

8 Status¶

Speaker: Qibin LIU (TDLI, SJTU)

9 Status¶

Speaker: Ngoc Khanh Vu (TDLI, SJTU)

10 Status¶

Speaker: Rui Yuan (TDLI, SJTU)

DarkSHINE:

HCAL: 

• revise some study from baseline 1.0 to 1) finalize CDR 2) figure out how to define the HCAL energy calibration scale
• prepare SiPM board for mini-prototype test

 

Hzy/Hyy*:

• update internal note

11 Status¶

Speaker: Tong Sun (TDLI, SJTU)

  

positron on target:

• estimate nBkgs with rare processes and inclusive_truthfilter samples for signal brem selection, and compared that of  e+OT and e-OT.
• plan to use XGBoost to separate bkg and signal

other:

• review a BESIII memo: lambda -> nKS0pi+

REU: Undergrad Research Discussions¶

12 Status¶

Speakers: Fengyi Jiang (ShanghaiTech Univ. (CN)), Sian Yang (ShanghaiTech University)

default(2).yaml

ratio of in-signal region signal and background events:

Not enough total events generated, will apply for bl0 account. 

BUG:

How to reproduce: 

1. use the attached default.yaml, run Dsimu.
2. Dana

Dana will crash at 255th event.

Error raised: PFTopoCluster_analysis.cpp line 219, complains that vector of length 0. 

Should be related to Cluster_Analysis of Dana or some bug of DSimu that generates an invalid event.
