Overview

  • high electron identification with shower shape
  • electron ID cuts
    • # of cluster > 100
    • # of ITS ; 3
    • -1<nSigma<3
    • TPC, ITS refit
    • TPC cluster ratio ; 0.6
    • SPD hits ; kAny
    • Centrality ; 0-10%

Shower shape

  • E/p vs. Shower Shape (pT>10 GeV/c)

  • Shower shapes with different E/p cut
    • E/p>0.9 (red) --- electron candidate
    • E/p<0.9 (blue) --- hadrons
