Phys. Rev. Lett. 75, 2650–2653 (1995)Candidate Events in a Search for ν̅ μ→ν̅ e OscillationsReceived 19 April 1995; revised 12 June 1995; published in the issue dated 2 October 1995 A search for ν̅ e's in excess of the number expected from conventional sources has been made using the Liquid Scintillator Neutrino Detector, located 30 m behind the Los Alamos Meson Physics Facility beam stop. The ν̅ e are detected via ν̅ ep→e+n with e+ energy between 36 and 60MeV, followed by a γ ray from np→dγ ( 2.2MeV). Using strict cuts to identify γ rays correlated with e+ yields 9 events with only 2.1±0.3 background expected. A likelihood fit to the entire e+ sample results in a total excess of 16.4-8.9+9.7±3.3 events. If attributed to ν̅ μ→ν̅ e oscillations, this corresponds to an oscillation probability of ( 0.34-0.18+0.20±0.07)%. © 1995 The American Physical Society URL:
