Track matching study from TPC to PHOS in ALICE

We present a study for matching charged tracks reconstructed from the ALICE tracking detectors with the clusters measured in the photon spectrometer.Matching efficiency and contaminations due to wrong matches have been deduced for charged pions and muons.For electrons,the effect of the material in front of PHOS is discussed.
