Measurement of nu[subscript mu] and nu[over-bar][subscript mu] induced neutral current single pi[superscript 0] production cross sections on mineral oil at E[subscript nu]∼O (1 GeV)

Abstract

MiniBooNE reports the first absolute cross sections for neutral current single pi0 production on CH[subscript 2] induced by neutrino and antineutrino interactions measured from the largest sets of NC pi0 events collected to date. The principal result consists of differential cross sections measured as functions of pi0 momentum and pi0 angle averaged over the neutrino flux at MiniBooNE. We find total cross sections of (4.76±0.05stat±0.76sys)×10-40 cm[superscript 2]/nucleon at a mean energy of (E[subscript ν]⟩=808 MeV and (1.48±0.05stat±0.23sys)×10[superscript -40] cm[superscript 2]/nucleon at a mean energy of ⟨E[subscript ν]⟩=664 MeV for ν[subscript mu] and ν[over-bar][subscript mu] induced production, respectively. In addition, we have included measurements of the neutrino and antineutrino total cross sections for incoherent exclusive NC 1pi[superscript 0] production corrected for the effects of final state interactions to compare to prior results.
