PID July 2007 Notes

Summaries of talks presented at the workshop are available on the portal and/or linked from the agenda page on the Wiki. Below is a summary of action items from the workshop. Action items were grouped into several broad categories

BCAL

• Complete analysis of the test beam data and present at October collaboration meeting. (Regina/Athens/Alex) Particular attention should be paid to:
  • understanding the large floor term in the resolution that appears at high energy and forward angle.
  • understanding the light output and attenuation length of the fibers for the sake of setting realistic thresholds in reconstruction.
• Demonstrate that SiPMs meet the necessary performance benchmarks. (Regina)
• Quantify the number of TDC channels needed in BCAL (Zisis)
• Explore the possibility of doing dE/dx in the BCAL (Zisis)
• Determine need for BCAL signal splitting and discriminators

FCAL

• Examine the low energy threshold used for the FCAL in Monte Carlo (IU)
• Understand the effect of and method to deal with radiation damage in the FCAL (IU)

Full Monte Carlo

• Develop a method for incorporating Pythia-generated hadronic backgrounds into the simulation (Dave/Eugene) done!
• Examine the purity of all neutral events in the presence of hadronic backgrounds. Can final states like ηπ⁰ be cleanly identified? How much do kinematics fits help to select these topologies? (Matt/Matt/Mihajlo)
• Perform a toy amplitude analysis on γp→ηπ⁰p to understand impact of FCAL/BCAL acceptance in amplitude analysis (Matt/Matt/Mihajlo)
• Modify geometry description to reflect most recent design which includes changes to: (Richard/Dave)
  • FDC
  • CDC endplate and inner radius
  • start counter
  • Cherenkov snout
