Title:     A Measurement of Neutrino Induced Charged Current Neutral Pion Production at MiniBooNE

Abstract: The Mini-Booster-Neutrino-Experiment at Fermilab has recorded the largest sample of muon neutrino interactions (~1,000,000) at the 1 GeV scale on a nuclear target (CH2) to date.  This allows for the precise measurement of many neutrino cross-sections that will aid in the understanding of event rates in future oscillation searches (such as T2K).  I will discuss an overview of the MiniBooNE suite of cross-section measurements with particular focus on charged current neutral pion production (CCpi0).  This measurement required the design of a specialty fitter to reconstruct the muon and the pion in the event where the pion is found from the Cherenkov rings produced by its daughter photons.   This fitter reconstructs all three Cherenkov rings in the event.  This allows for the measurement of many kinematic quantities, most importantly the incident neutrino's energy.   With this measurement we can report various, previously unmeasured, differential cross-sections along with the total CCpi0 cross-section as a function of neutrino energy.

Stimulants available 15 minutes before the talk.
