Abstract

We reanalyze the recent data from the Liquid Scintillator Neutrino Detector (LSND) experiment that might indicate \ensuremathν_\ensuremathμ\ensuremath↔\ensuremathν_e mixing. This indication is not completely excluded by the negative results of established accelerator and reactor neutrino oscillation searches. We quantify the region of compatibility by means of a thorough statistical analysis of all the available data, assuming both two-flavor and three-flavor neutrino oscillations. The implications for various theoretical scenarios and for future oscillation searches are studied. The relaxation of the LSND constraints under different assumptions in our statistical analysis is also investigated.
