Notes for the Discussion:

PID/Delphes

• PID systems: an mRICH (backward/lepton direction), a barrel DIRC, and a dual RICH (forward/hadron direction).
• Implemented using Yellow Report-era EICUG tools ("PID Code") which returns nSigma separation for a particle with a given (p,theta) under a certain hypothesis pair (e.g. K/pi or K/proton).
• Run PID Code -> feed it particles across a range of (p,theta) -> use accept/reject method to compute efficiency given nSigma -> generate IdentificationMap objects in Delphes.
• These are already available in https://github.com/eic/delphes_EIC, particularly in the delphes_card_allsilicon_3T.tcl card.
• Planned studies
  • Sekula: charm jets and use of kaon ID to assess jet tagging performance
  • Elke suggested overlaying on the Delphes ID maps an additional matrix of performance degradation with the number of tracks within a certain spatial region of each single track -> good to do item -> look to LHCb for guidance on this.
