Speaker: Rui Yuan (TDLI, SJTU)

DarkSHINE HCAL:

variables for BDT validated and added to the DAna framework, performance has been shown by Zhiyu

 

Hyy*/zy:

 

update note, response the CDS comments and EB request meeting comments, gave report for summary of status&response on HIGP photon sub-group meeting

 

H2a4b:

signal sample validation of H->2a LLP & semi LLP, solved the issue of H->a1a2 decay

 

 

Taking shift

11:30 → 11:40 Status

Speaker: Tong Sun (TDLI, SJTU)

positron on target:

√ calculated signal efficiencies for bremsstrahlung: 46% ~ 68%

√ biasing study to get EOT by Xuliang

√ validation of inclusive  and rare process samples 

√ estimated nBkg with inclusive sample (2.5e9 POT): 0.156 (baseline1.0:  0.0025)

√ estimated bkg with  rare process samples: 0.1

         

To do:

• estimated bkgs on t-ch and s-ch signal region and then calculate signal efficiencies
• calculate total limit by combine three signal channels
