Outlook

  • Studied E/p and Shower shape with titer matching cut (R<0.003) and wider cut (R<0.02) in the central trigger

General

  • trigger selection ; central trigger (centrality 0 - 10 %)
  • dE/dx cuts in this analysis is 72 - 90 (see dE/dx vs. E/p)
  • E/p cut for electron selection ; |nSIgma|<2

E/p with matching cuts

Shower Shape Comparison (R<0.003 vs. R<0.02)

  • Electron candidate
  • required # of matched track = 1 / cluster
  • Comparison between R<0.003 cut and R<0.02 cut
  • Distributions are normalized with the # of entries

# of cells

Summary

  • R<0.02 cut result have more # of cells / cluster than R < 0.003
  • R<0.02 cut result make a longer tail in shower shapes (M02, dispersion)
