Dark Photon Combination:

• EB formed, 1st EB meeting will be in the week of March 11. 
• Added a dummy flat systematic uncertainty of 35% for masses >= 1.5TeV in VBF-channel to account for the residual discrepancy between recast and HEPdata.
• Final combination results (work with Qibin): Best limit at LHC.
• Finalize the INT note and contribute to the paper draft targeting PRL.

Xbb tagging g->bb calibration:

• Updated the Ntuple Analyzer code to select g->bb candidate in the event and categorised into pT bins, ljet flavours, and Xbb-tag.
• First check with GN2Xv00 80% WP. Good data/MC agreement across different pt bins. 
• Will perform the fit with only stat. uncertainty for all each pt bin.
• Test the full workflow the GN2Xv01 (which is official now)

Run-3 dark photon search: Ntuples production, build up the trexfitter config file.

Speaker: Rui Yuan (TDLI, SJTU)

not many results in this week, several on-going tasks:

H2a4b: validate the new exclusive ggZH/qqZH lhe files decay, submitting the new production request

Hyy*: trying to prepare code for the background fit

DarkShine: some investigation, work with Chunxiang to prepare prototype simulation package.
