13:50 Simulation and analysis

Speaker: Yufeng Wang (TDLI)

• Baseline 1.6 production pending for (1) ACTs reconstruction (2) low-energy hit removal in ECAL clustering.
• Vertical/horizontal placed tracker has little impact on acceptance. 
• Thickness of tracker has different effect with signal mass, i.e., recoil electron energy. Hit energy filter @ 20 keV might be too tight for 1 MeV signal. Need to check:
  • truth-level process type
  • truth-level track number

14:00 → 14:30 ATLAS performance and physics

14:00 ttW/ttH -> multi-leptons analysis

Speaker: Jialin Li

1. Checked the bad（missed branches）samples and redo the injection.
2. Submitted the v0901 GFW1 jobs with ttH PDF uncertainty. 
3. Add ttV xs and update others' xs and do fit again. 
4. Produce the post-fit plots of mva-variables and update on Inernal note.

14:10 Electron/photon performance, H->Zgamma and gg* analysis

Speakers: Danning Liu (TDLI/SJTU), Kang Liu, Rui Yuan (SJTU)
