New Anti-Neutrino Cross-Section Results from MiniBooNE

Abstract

The first measurements of antineutrino charged-current quasielastic ($\text{numub}$ CCQE, $\text{numu}+N\to \text{mup}+N^{\prime }$) and neutral-current elastic ($\text{numub}$ NCE, $\text{numu}+N\to \text{numu}+N$) cross sections with $<E_{\bar{\nu }}>$ $<$ 1 GeV are presented. To maximize the precision of these measurements, many data-driven background measurements were executed, including a first demonstration of charge separation using a non-magnetized detector. Apart from extending our knowledge of antineutrino interactions by probing a new energy range, these measurements constrain signal and background processes for current and future neutrino oscillation experiments and also carry implications for intra-nuclear interactions.
