1304.7395 (Joseph Grange et al.)

New Anti-Neutrino Cross-Section Results from MiniBooNE    [PDF]

Joseph Grange, Ranjan Dharmapalan for the MiniBooNE Collaboration
The first measurements of antineutrino charged-current quasielastic ($\numub$ CCQE, $\numu + N \to \mup + N'$) and neutral-current elastic ($\numub$ NCE, $\numu + N \to \numu + N$) 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.
