Abstract
A search for ν¯μ → ν¯e oscillations has been conducted at the Los Alamos Meson Physics Facility by using ν¯μ from μ+ decay at rest. The ν¯e are detected via the reaction ν¯e p → e+ n, correlated with a γ from np → dγ (2.2 MeV). The use of tight cuts to identify e+ events with correlated γ rays yields 22 events with e+ energy between 36 and 60 MeV and only 4.6 ± 0.6 background events. A fit to the e+ events between 20 and 60 MeV yields a total excess of 51.8+18.7−16.9 ± 8.0 events. If attributed to ν¯μ → ν¯e oscillations, this corresponds to an oscillation probability of (0.31+0.11−0.10 ± 0.05)%. © 1996 The American Physical Society.
