CCpi0 events at MiniBooNE

Charged current neutral pion events are the fourth largest exclusive sample of neutrino interactions at MiniBooNE, constituting about 4\% of total neutrino interactions. The study of this sample is interesting in several respects. First, at MiniBooNE energies ($\sim1$GeV) the cross section is known with only modest precision. Second, there is no coherent cross- section in this channel, and therefore the low $Q^2$ behavior differs from that of the CC$\pi^+$ channel. Finally, if one wants to use CC$\pi^+$ events for $\nu_e$ appearance studies, CC$\pi^0$ events are a large background. The study of this data sample in MiniBooNE is complicated by the fact that a full kinematic reconstruction requires simultaneously reconstructing three Cherenkov rings. We will report on the recent progress in the reconstruction and study of these events.
