New MiniBooNE Oscillation Result*

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.
