Outlook

  • EMCal trigger data (EMCEGA) with Lego train
  • 55 runs are satisfied good quality
  • 3 runs were failed and 30% jobs are failed
  • 2M events were used for this analysis

Results

Check the performance of electron identification with TPC and EMCal

  • looked at TPC nSIgma and E/p to check the performance
  • both detector doesn't request Tender (not need)
  • required pT > 5 GeV/c

  • All Centrality
Pic_NsigEop_All.png

  • Centrality 0-5 %

E/p distribution

  • Centrality 0-5 %
  • requested -1.5 > nSigma
  • below pT<10 GeV/c, the cut is fine
  • pT > 10 GeV/c, need more tighter cut to get pure electron sample

E/p (eta and phi dependence)

  • integrated centrality 0 - 10% to increase the statistics

Raw electron yields in the most central collisions

  • required nSigma TPC > -1.5
  • not corrected hadron contamination
