Kun's weekly group discussion

Wednesday 21 Feb 2024, 13:30 → 15:00 Asia/Shanghai

Tsung-Dao Lee Institute/N5F-N531 - Discussion Room (Tsung-Dao Lee Institute)

13:30 → 14:00 DarkSHINE tracker, analysis and simulation

13:30 Tracking detector R&D

Speaker: Kang Liu

I will arrange a new test time to complete the IV and CV tests with junhua, yanglin, and yudian.

13:40 Tracking reconstruction

Speaker: Junhua Zhang

To do:

Write a more detailed technical manual for the probe station and ammeter.

Discussion with Prof.Yang Yong

Before Mar.2 , complete all work of seeding algo in ACTS

13:50 Simulation and analysis

Speaker: Yufeng Wang (TDLI)

• some samples produced to find a reasonable hit energy cuts.
• baseline 1.6 analysis
  • reconstruction: tracking (with ACTs), ECAL clustering
    • signal/background event identification
  • analysis selection optimization with changed detector geometry, trigger/filter and reconstruction
  • background estimation with larger statistics:
    • functional extrapolation with trigger and filter
    • machining learning - study the energy distribution of ECAL & HCAL
  • systematics from reconstruction and background yield estimation

14:00 → 14:30 ATLAS performance and physics

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

Speaker: Jialin Li

Reported the 2lSS0tau result on the 4th EB meeting. HIGG-2022-03 ttH multileptons 2015-2018 (8 February 2024) · Indico (cern.ch)

Next to do: Reply to EB questions in the next week.

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

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

Kang

For Photon ID with EE method: 

I'm updating the system uncertainty and will report it in tomorrow night.

For Zy Analysis:

signale ntuple can be completed in the very near future. There is a problem with the grid job of bkg ntuple. I will try to solve it.

14:30 → 14:50 Round table

Speakers: Dian YU (Tsung-Dao Lee Institute), Lin Yang (TDLI), Zhiyang Dai

Dian:

1. Previous problems connecting to the instruments fixed. Easy requests like print serial number can be done.
2. Some issue when making more complex requests encountered. Discussing about bug fixes with USTC.

 

Lin:

1. Circuit diagram for I-V Test
2. di-Higgs Production articles
