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.
