Monte Carlo studies

Monte Carlo studies

• Calo response
• Energy sharing between towers
• Sampling fraction
• Effects of materials in front of detector
• Backgrounds in pi0 mass spectrum
• Pre/post shower response
• Slow simulator photo stats
• SMD cross talk simul. Fibers outside det.

2
Algorithms

• Separated tower
• Adjacent towers
• Single tower
• Finding best pair vs. combinitorics
• Fitting vs cluster picking
• Energy sharing algorithms
• Eta dependence of tower sizes
• Single energy and length cuts dont make sense!
• Pre/post shower to help with tpc showering pi0s
• TPC tracks?
• Direct gammas

3
Efficiency

• Embedding
• Event mixing
• Pythia
• Pi0 correlated with other particles in jet

4
Misc.

• Shape analysis for high energies
• Test beam data
• Au/Au data
• Comparisons and improvements in barrel algo. for
  spin
• Organization meeting every other week opposite
  barrel pi0 meeting?

5
Goals

• PRC on endcap pi0 ALL by june barrel too?
• Anamolous pi0 ratios by aug 05
• 2 part. Correlations with endcap trigg part.
• use high tower as trigger particle
• Ready to analyze 2005 data as soon as
• data available
• SMD NIM article
