Overview

Hadron subtraction at high pT (EMCEGA)
estimated the shape with hadron candidate

E/p distributions

E/p distribution
- -1<nSigma<3 (electron)
- nSigma <- 3.5 (hadron)
nSigma < -3.5 represent background shape

E/p after subtracting nSigma < -3.5

E/p mean and Sigma

Hadron contamination

Hadron contamination level about 10 % with -1<nSigma<3 and 0.9 < E/p < 1.3

Raw electron spectrum after subtracting Background

( 0.9 < E/p < 1.3)
