A Search for Electron Neutrino Appearance at the Delta m**2 ~ 1 eV**2 Scale


Abstract in English

The MiniBooNE Collaboration reports first results of a search for $ u_e$ appearance in a $ u_mu$ beam. With two largely independent analyses, we observe no significant excess of events above background for reconstructed neutrino energies above 475 MeV. The data are consistent with no oscillations within a two neutrino appearance-only oscillation model.
