A search for ν̄μ→ν̄e oscillations was conducted by the Liquid Scintillator Neutrino Detector at the Los Alamos Neutron Science Center using ν̄μ from μ+ decay at rest. A total excess of 87.9±22.4±6.0 events consistent with ν̄ep→e+n scattering was observed above the expected background. This excess corresponds to an oscillation probability of (0.264±0.067±0.045)%, which is consistent with an earlier analysis. In conjunction with other known limits on neutrino oscillations, the LSND data suggest that neutrino oscillations occur in the 0.2-10 eV2/c4 Δm2 range, indicating a neutrino mass greater than 0.4 eV/c2. ©2001 The American Physical Society.
