SCIENCE BRINGS NATIONS TOGETHER simulation studies #29

Wednesday 3 Dec 2025, 21:00 → 22:20 Europe/Moscow

zoom: https://cern.zoom.us/j/68545205504?pwd=VWxlVzF0ZnptU01zNG1qbDBLRGljUT09

- Alexandra: pick up Sonja's simulation n_overflow vs P(proton) for 25ns 800 mV cut and get 
      - MPV vs P(proton), Sigma vs P(proton)
      - n_overflow vs dE
- Katerina - contact Solin
- Sasha Nartov
    - technical part
        - prepare for accounting overflow
        - for accounting underthreshold (hit weight=0)
        - wait for Alexandra
    - muons, pions, kaons, protons, (electrons) - ( 1), 0.5, (0.3) GeV/c
        - average over track (already exists)
        - trimmed mean (30% of highes value) 
       - 1D histo per P (all particles) - trimmed mean(ver1) not treamed mean (ver2), 2D histo (scatter plot) for P-dependence
       - 90 (40, 26) 
- Sasha Lazorev - validation of updated Katja's version
       - efficiency to be added
       - bug to be fixed
   - as soon as donne - minBias, get access to tracks, select tracks for given dP
   - instead of theta of MC_point it is better to use theta of the track 
   
 
 next meeting - dynamically, but not later than in a week :)
