Single-pion production cross sections at MiniBooNE

Abstract

The MiniBooNE experiment has prepared an almost pure beam of muon-neutrinos over an energy range of a few-hundred MeV to a few GeV with a sample of roughly one-million neutrino interactions. Detailed cross-section measurements have been performed spanning 89% of the total neutrino-interaction rate. Specifically, three single-pion production mechanisms have been measured in detail. These measurements are important for a myriad of reasons: Neutral-current neutral-pion production is an important background for electron-neutrino appearance searches, Charged-current charged-pion production is the single largest background for quasi-elastic scattering and also provides the purest sample of events at these energies, and charge-current neutral-pion production provides a pure measure of incoherent pion production. Each of these processes required custom event reconstructions due to the particulars of the final-state particles. In addition, the sample selections and analyses will be discussed in detail. Many single-pion cross-section measurements, and their possible implications will be presented.
