• VHWW 3rd EB meeting last Thursday:
  • Presented the strategy on WZ CRs in 2l same sign and 3l channels
  • Working together with another colleague to include the fake factor and electron charge flip scale factor systematics in the 2l same sign channel
• Improve the slides for the talk in NUCLEUS – 2021 and prepare for the rehearsal tonight
• (Sorry to leave earlier since I am watching Hanlin's thesis defense now)

09:41 Mario Jose Sousa

Speaker: Mario Jose Sousa (University of Science and Technology of China (CN))

HN: derivations for new signals requested and nearly finished.

VBS:
* present fit status last Monday in the meeting:
-- https://indico.cern.ch/event/1075499/
-- MCstat / systematic expected significance is now consistent.
-- Some differences found between running 3 POI combined fit and single lepton channel fits
* running updated fits (full Run-2 dataset for 0 lepton).
* some missing variables identified in 1-lepton inputs.

HGTD demonstrator: no news.

HGTD testbeam:
* Discussion with conveners last Wednesday after meeting.
* Preparing code to run over trees.

HGTD general: Next (long) week is HGTD week but Electronics/Mechanics parallel sessions overlap with USTC meeting: not in either group so I will be present here.

AOB: ADCoS shift last Monday.

MaxVariationIn10x10Range_flatness_RO_Panel1.png

1. check the flatness of the readout panel.

In general, the flatness satisfy our need.

2. Based on the LHE files provided by Mingyi, I will do the comparing with the distribution provided by theorist. I hope I can get preliminary results tonight.
