Speaker: Xuliang Zhu (TDLI, SJTU)

DarkSHINE:

• Positron paper writing (WIP)
• SideHCAL Geometry (WIP)
• PN ECAL production (30%)

Dr. Sai:

• Code Cleanning / debug Agent (WIP)
• GRPO code

 

10:40 → 10:50 Status

Speaker: Zhiyu Zhao (TDLI, SJTU)

1. Design and optimization of DarksSHINE ECAL electronics, towards prototype
   • provide more details of requirements on electronics part, according to energy resolution specification
2. DarkSHINE v1.6 analysis with TMVA
   • current BDT offers 1-order of magnitude advantage than cutflow method, further improvment is ongoing 
   • try other mechine learning methods, like GNN and transformer

HCAL:

test of new bars, (somehow 2 SiPM board was broken and re-make other two for test)

 

H2a4b:

work with Zelin for 1st version of SR/CR definiation

study the weird structure of h_pt in LLP sample

 

Hyy*/zy

 

yy*: working on testing the MxAOD in rest procedure (Sig PDF +  bkg PDF)

zy: adding bkg modeling result (obtained from a MC distribution after smoothing) to final WS, so far it will cause the fit failing to converge, debuging on that

Speaker: Linjing Duan (Sun Yat-sen University, Shenzhen Campus (CN) & TDLI/SJTU (CN))

1. Plot histograms of ptgamm and missing energy from the Ntuple generated by the Standard Model.
2. Plot histograms of these two variables from the Ntuple of the remaining signal events.
3. Process the updated background sample and generate the Ntuples.
