Description

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