Overview

  • Compared raw electronspectrum with/without M20 cut
  • Hadron contaminations were estimated by using E/p (nSigma<-3.5) in both case
  • EMCal trigger (0-10%)

Results

  • Hadron contamination in the spectrum with/without M20 cut

  • Raw electron spectrum with/without M20 cut after background subtraction

  • with M20<0.3, we improve the hadron contamination around 10%, but not lose electrons
