Title:     Significant Excess of Electron-Like Events in MiniBooNE

Abstract: The MiniBooNE experiment at Fermilab observes an excess of 460.5+-99.0 nue CCQE candidate events in the 200 < E < 1250 MeV energy range, corresponding to a significance of 4.7 sigma. If interpreted in a two-neutrino oscillation model, numu -> nue, the best oscillation fit to the excess has a probability of 21.1%, while the background-only fit has a chisquare probability of 6E-7 relative to the best fit.  The MiniBooNE data are consistent in energy and magnitude with the excess events observed by the LSND experiment. Although the data are fit with a two-neutrino oscillation model, other models may provide better fits to the data.
