Abstract

A 20-ton neutrino detector located near the Los Alamos Meson Physics Facility beam stop is used search for ν̄e generated via neutrino oscillations from any of the three neutrino types, νμ, ν̄μ, and νe, which radiate from the beam stop. The analysis of three years of data provides limits on the oscillation modes ν̄μ→ν̄e, νe→ν̄e, and νμ→ν̄e, and the lepton-number-violating decay process μ+→e++ν̄e+νμ. The 90%-confidence-level limits for ν̄μ→ν̄e oscillations are δm2≤0.14 eV2 for maximal mixing, and sin22θ≤0.024 for large δm2. © 1993 The American Physical Society.
