Run-3 inclusive H->yyd search:

• With Run-3 data-only: reoptimize SR with vertex-BDT added and using new MC23c samples.
• Check mt-binned fit and met-binned fit. Plot Significance s/sqrt(b)-vs-met.
• After break, perform the ggF H->yyd search with Run-2 data (same selections, same bkg estimation). If the Run-2 sensitive is comparable, try a Run 2 + 3 combination. 

HWWlvlv QE:

• Working with Baihong on the trigger study: find the best trigger OR combinatory for same-flavor and different-flavour regions (S/Sqrt(B), trigger eff.,, etc). Using FastFrames for ntuples post-processing step (cutflows, histograms, etc.).

MDT gas system (with Philipp):

• Perform the annual leak rate measurements.
• For chambers with increasing leak rate, find what causes the leak and fix.

DarkSHINE:

HCAL variables for 4GeV BDT analysis: add variable reconstruction to DAna, a little bit validation is on-going and will merge to Zhiyu's part asap

mini-prototype: making the front board （Sipm+pre-amplifer）,  had some mistake on the current one, 

 

Hzy/yy*:

updating the bkg modelling results/internal note for EB request. In order to catch up the request, study here was ...naive... detailed study is on-going. (In current version, a smooth procedure was implemented, which was not prefered due to the big statistics of fastsimulation for Run3)

 

H2a4b:

A status report was presented last week by Zelin, further talk with conveners is needed, in principle they still hope there could be more person power for tagging study but agree us to try some BDT directly to speed up the analysis

11:40 → 11:50 Status

Speaker: Tong Sun (TDLI, SJTU)

positron on target:

• estimated the bkg with inclusive sample on bremCut:  0.029 

• the signal efficiencies of bremsstrushlung is 46%~68% 
• To-do:
  • to generata rare processes and t-channel and s-channel signal sample
