Abstract:
The preliminary P0D pizero reconstruction efficiency has been calculated using a detailed detector simulation and reconstruction base on the first set of ND280 reconstruction algorithms. The primary reconstruction is done using the P0D Shower and sbcat fitters. Events with separated tracks (e.g. EM shower candidates) and without tracks consistent with muons are selected. For an exposure of 1x10^21 protons on target, the expected sample is approximately 13,600 events. The signal [as defined in the note] will contribute about 76% of the final sample
