A measurement of the neutrino neutral current pion cross section at MiniBooNE

The MiniBooNE neutrino beam and detector at Fermilab are used to study the production of neutral current pi0 events. The cross sections for neutrino interactions with mineral oil (CH2) are reported for resonantly produced and coherently produced single pi0 events. We measure a resonant single pi0 cross section of sigma(nu mu N → numu N pi0) = (0.0129+/-0.0011 (stat.)+/-0.0043 (syst.)) x 10-36 cm2/CH 2 at a mean neutrino energy of 1.26 GeV. We measure a coherent single pi 0 cross section of sigma(numu A → numu A pi0) = (0.00077+/-0.00016 (stat.)+/-0.00036 (cyst.)) x 10-36 cm2/CH 2 at mean neutrino energy 1.12 GeV.
