N2 - Single π0 production is the one of the most important backgrounds in the υe appearance measurement in T2K. Large uncertainties in this production make it difficult to predict. Measurement at the near detector (ND280) is required both to constrain the background prediction at the far detector (Super-K) and also at the near detector to improve knowledge of beam υe contamination. We present an analysis based on Monte Carlo simulation of neutral current (NC) single π0 in the tracker region. NC-1π0 events are selected using a specific two-gamma signature in the tracker region. One decay gamma is reconstructed by selecting an e+/e- pair starting in the Fine-Grained target Detector (FGD) and extending into the TPC, where the leptons can be identified and their momentum measured accurately. The second gamma is then selected in-time in the Calorimeter modules surrounding the tracker.
