Outline

  • Studied systematic uncertainty from photonic electron reconstruction efficiency

Uncertainty from pi0 pT shape

  • pi0: assuming same as charged pion. Took from analysis note of 2010 HFE Raa TPC+TOF
    • measurement was up to 20 GeV/c. extend the curve to get the efficiency
  • charged particle: took from charged particle Raa (2011 preliminary) 0-5 % centrality
  • /u/shingo/WRK_eliza8/2012/11/11/LEGOMC66

  • applied 8% on the efficiency
