Photon ID

[done works]

• electron flattening with necessary event-level selections
  • mass cut
  • probe: fixed-cut-loose isolation req.
  • add photon conversion information
  • tag: tight_ID, HLT (obj-pre)
  • jet: isolation req. (obj-pre)
  • tracking criteria (obj-pre)
  • eta cut, i.e., crack region exclusion (obj-pre)
  • pt cut (obj-pre)
  • trigger requirement (obj-pre)
  • at least 2 electrons with opposite charges
  • at least 1 probe electron
• ele mc weight
  • lumi information
  • sum weight
  • xsec information
• photon skimming
  • jet veto
  • truth match
  • isolation req.: FixedCutLoose
  • pt and pseudorapidity cut
• ROOT-to-H5 conversion
• training based on unchanged model parameters

 

[to-do list]

• model optimization
