Please edit this page! Write answers to the questions. Add more questions. Also please link any relevant technical document or talk to this page so we can use it as a resource during discussions.



Neutral Particle PID Questions

  • What is needed to develop a MC with realistic efficiency and resolution for neutrals that includes appropriate backgrounds from photon conversions?
    • appropriate detector/electronics response must be included in simulation
    • an operational reconstruction algorithm must exist in the software framework
    • simulation must include a realistic picture of the material in front of the calorimeters

BCAL

Documentation/Talks/Links

Discussion Points

Detector Response

  • What input is needed to validate the detector response in the Monte Carlo?
  • What is the status of the beam test analysis that can provide (some of) that input?

Reconstruction

  • What is the status of the reconstruction algorithm in the MC?
  • What is the best method for tuning and improving this algorithm?

Material Budget

Documentation/Talks/Links

Discussion Points

  • Is the material picture accurate?
  • Are we considering alternate material descriptions?
  • What is the status of these investigations?


FCAL

Documentation/Talks/Links

Discussion Points

Detector Response

  • How accurate is the detector response in the Monte Carlo?
    • it currently does not include photo-statistics, can/should this be improved?
    • response will need tuning after beam test

Reconstruction

  • What is the status of the reconstruction algorithm in the MC?
