# of events in the analysis

  • EMCal trigger (all the centrality) ; 250,000
  • Central trigger ; 2,000,000

Energy distribution

Energy distribution in EMCal trigger

Comparison Max tower Energy and All cluster in EMCal trigger

Pic_eop_fit_expgau_v2.png"

  • Maximum tower energy distribution is identical with cluster energy distribution without any trigger cluster selection above the threshold.
  • In most central, these distributions are different above the threshold

Comparison between EMCal trigger (Central) and Central trigegr

Pic_eop_fit_expgau_v2.png"

  • Cluster energy distribution with the EMCal trigger in the most central (0-10%) is well match with the distribution with the central trigger after arbitrary scale above the threshold.

E/p

Central trigger

Pic_eop_fit_expgau_v2.png"

  • Large hadron contamination at low pT due to dE/dx selection. Need to check.

E/p peak position & resolution

Pic_eop_fit_expgau_v2.png"

  • peak position ; ~ 7 % higher than unit

Raw Electron yields

Central trigger (uncorrected background)

  • Uncorrected background hadron correction

Next to do

  • shower shape
  • track matching
  • phi and eta dependence of PID (E/p, dE/dx)
