EEmc Gammas via conversion method, losses due to cuts

EEmc Gammas via conversion method, losses due to cuts

Abstract:  We investigate losses in a single-photon MC event sample due to cuts applied in the conversion method.  We find that most of the (potentially recoverable) losses are due to the "hadronic veto" cut using the postshower detector.

EEmc Gammas via conversion method, systematics

 

Abstract: We investigate the systematic uncertainties associated with the conversion method.  Specifically, does the Monte Carlo indicate that the efficiency for passing the preshower-2 cut depends significantly on either pT or eta?

Abstract: Using the conversion method discussed previously, we examine shower-shape variables in greater detail. Specifically, we compare χ2/ndf distributions using shower-shapes derived from MC and from identified η decays.
