Title: Measurement of the neutrino component of an antineutrino beam observed by a nonmagnetized detector

Abstract

Two methods are employed to measure the neutrino flux of the antineutrino-mode beam observed by the MiniBooNE detector. The first method compares data to simulated event rates in a high-purity {nu}{sub {mu}}-induced charged-current single {pi}{sup +} (CC1{pi}{sup +}) sample while the second exploits the difference between the angular distributions of muons created in {nu}{sub {mu}} and {nu}{sub {mu}} charged-current quasielastic (CCQE) interactions. The results from both analyses indicate the prediction of the neutrino flux component of the predominately antineutrino beam is overestimated--the CC1{pi}{sup +} analysis indicates the predicted {nu}{sub {mu}} flux should be scaled by 0.76{+-}0.11, while the CCQE angular fit yields 0.65{+-}0.23. The energy spectrum of the flux prediction is checked by repeating the analyses in bins of reconstructed neutrino energy, and the results show that the spectral shape is well-modeled. These analyses are a demonstration of techniques for measuring the neutrino contamination of antineutrino beams observed by future nonmagnetized detectors.
