Unexplained Excess of Electron-Like Events From a 1-GeV Neutrino Beam

PDF Version Also Available for Download.

Description

The MiniBooNE Collaboration observes unexplained electron-like events in the reconstructed neutrino energy range from 200 to 475 MeV. With 6.46 x 10{sup 20} protons on target, 544 electron-like events are observed in this energy range, compared to an expectation of 415.2 {+-} 43.4 events, corresponding to an excess of 128.8 {+-} 20.4 {+-} 38.3 events. The shape of the excess in several kinematic variables is consistent with being due to either {nu}{sub e} and {bar {nu}}{sub e} charged-current scattering or to {nu}{sub {mu}} neutral-current scattering with a photon in the final state. No significant excess of events is observed in ... continued below

No significant excess of events is observed in the reconstructed neutrino energy range from 475 to 1250 MeV, where 408 events are observed compared to an expectation of 385.9 {+-} 35.7 events.
