- May 2007 PID Workshop
- Physics Goals and Performance Metrics
- Neutral Particle PID May 2007
- Charged Particle PID May 2007
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
- status of simulation and reconstruction of photons (George/Zisis/Mihajlo)
- analysis of test beam data (Blake/George/Zisis)
- Blake's Preliminary Timing Resolution Report
- BCAL Beam Tests 2006 - Analysis; shows progress in the analysis by Blake
- BCAL Module 1 Specs
- BCAL Beam Tests - Hall-B, September 2006 (Master Wiki Page)
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?
Follow up
Walk Corrections
Sampling Fraction Resolution
Material Budget
Documentation/Talks/Links
- impact of FDC material on shower reconstruction/efficiency (Richard/Mihajlo)
- impact of FDC material on backgrounds (Matt)
Discussion Points
- Is the material picture accurate?
- Are we considering alternate material descriptions?
- What is the status of these investigations?
FCAL
Documentation/Talks/Links
- status of simulation and reconstruction of photons (Mihajlo)
- quantifying improvements in light collection efficiency (Matt)
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?
