Title: Significant Excess of Electronlike Events in the MiniBooNE Short-Baseline Neutrino Experiment

Abstract

The MiniBooNE experiment at Fermilab reports results from an analysis of $$\nu_e$$ appearance data from $$12.84 \times 10^{20}$$ protons on target in neutrino mode, an increase of approximately a factor of two over previously reported results. A $$\nu_e$$ charged-current quasielastic event excess of $$381.2 \pm 85.2$$ events ($$4.5 \sigma$$) is observed in the energy range $$200
