Phys. Rev. Lett. 81, 1774–1777 (1998)Results on νμ → νe Neutrino Oscillations from the LSND ExperimentReceived 10 September 1997; published in the issue dated 31 August 1998 A search for νμ→νe oscillations has been conducted with the LSND apparatus using νμ from π+ decay in flight. Two analyses observe a total of 40 beam-on high-energy (60–200 MeV) electron events consistent with the νeC→e-X inclusive reaction. This number is significantly above the 21.9±2.1 events expected from the νe contamination in the beam and the beam-off background. If interpreted as an oscillation signal, the observed oscillation probability of (2.6±1.0±0.5)×10-3 is consistent with the previously reported ν̅ μ→ν̅ e oscillation evidence from LSND. © 1998 The American Physical Society URL:
