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
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)
