EEmc Gammas via conversion method, relaxing the hadronic veto cut
Updated on Tue, 2008-03-25 15:40. Originally created by jwebb on 2008-03-21 14:51.EEmc Gammas via conversion method, relaxing the hadronic veto cut
Abstract: Based on a quick MC study I decided to try relaxing the hadronic veto cut (i.e. Epost(R<0.3) < 0.2 MeV) in order to try recovering statistics. However, the results indicate a problem with doing this. Specifically the yield extraction fails and fails badly -- many more gammas "found" than the total yield input into the algo. We investigate this by releasing the hadronic veto cut and examining the resulting transverse shower-shape quantities. We then develop new cuts to replace the hadronic veto.

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
Updated on Thu, 2008-03-20 18:41. Originally created by jwebb on 2008-03-20 18:41.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.
