Title: Evidence For Neutrino Oscillations at LSND

Abstract: Searches for __ ! _e [1] and __ ! _e [2] oscillations with the LSND experiment [3] at theLos Alamos Meson Physics Facility have been performed using __ from _+decay in ight (DIF) and __ from _+decay at rest (DAR), respectively. The 1993-95 DIF (1993-98 preliminary DAR) analysis _nds an oscillation probability of (2.6 _ 1.0) _ 10_3((3.3 _ 1.0) _ 10_3), with a probability of statistical uctuation equal to _ 1:1 _ 10_3( _ 4:1 _ 10_8). The most-favored _m2 range, takinginto account results at all experiments, is 0:2 < __m2 < _2 eV2.
