Description
"The photon energy resolution of the Electromagnetic Calorimeter of the BaBar detector at SLAC has been studied. The response of the calorimeter was investigated using single photons above 1 GeV from the reaction e+e- -> mu+mu-gamma. Initially a discrepancy was observed between Data and Monte Carlo simulated events. A smearing technique has been developed to correct this discrepancy, based on the Students t distribution. This smearing is validated using an analysis of B->K*gamma, where a significant improvement in the agreement between Data and MC energy distributions is observed. This technique has been implemented as a standard correction for BaBar analyses. "
