New MiniBooNE Oscillation Result
ORAL
Abstract
Over the last two years the MiniBooNE experiment at FNAL has double its neutrino data sample. An updated electron neutrino oscillation analysis will be presented with 12.84x1020 protons on target (POT) and in combination with the previous electron antineutrino data set of 11.27x1020 POT. A significant combined excess is observed for the electron-like charged current quasi-elastic events. The best fit for a simple two-neutrino oscillation model has a probability of 0.20, compared with a probability of 5x107 for the null hypothesis. The excess observed by the MiniBooNE experiment is consistent with the excess magnitude and L/E shape as reported by the Liquid Scintillator Neutrino Detector (LSND) experiment, indicating strong evidence for physics beyond the Standard Model.
