    Minutes of FCC-hh Calo meeting 16.10.2018:

     

    Discussion of plans after finished CDR summary document, towards finalising CDR comprehensive report until end of 2018.

     

    Lepton performances:

     

    Anna:

    • angular and pointing resolution
    • photon isolation
    • influence of pointing resolution on Haa
    • upstream material correction barrel, endcaps
    • review CDR LAr plots and resim/redo if necessary comparing to baseline layout
    • electronic noise estimation: finer eta + for optimised segmentation layout
    • optimise segmentation layout wrt layer thickness, phi and eta cell size (for PCB layout):
      • en resolution
      • pointing res
      • pi0/gamma distinction with BDT

     

    Jan/Coralie*:

      • Deep Neural Net for photon/pi0 separation w/ highly granular second layer and w/ electronics noise to compare with BDT results  

     

     

    Hadron performance:

     

    • HCal standalone performances finalised / updated in CDR overleaf

     

    • Combined EMB+HB pion reconstruction: 

     

    Coralie:

      • Benchmark method need to be checked, updated with correct sampling fractions (B field dependent!)
      • use of benchmark method + electronics noise within reasonable sized window, to compare with ATLAS testbeam results:
        • Determine total noise contribution expected from included cells 

     

    Jana/Coralie: 

      • Look into possible optimisations of single pions with topo-clusters in calibration and thresholds for PU0/PU200/PU1000

     

    Jan/Coralie*:

      • Deep Neural Net for single pions w/ electronics noise

     

     

    Jets:

     

    • need particle flow for reconstruction in B field —> postponed to post-CDR phase due to missing  tracks, lack of menpower

     

     

    *Coralie meeting with Jan 17.10., to check what is achievable until end of 2018.
