A search for neutrino oscillations in the muon neutrino to electron neutrino appearance channel at LSND

Neutrino mass has long been an intriguing and controversial question. This issue has received much attention due to its far-reaching implications in astrophysics. A search for {dollar}nusbmutonusb{lcub}e{rcub}{dollar} oscillations, which if seen, would imply neutrino mass, has been conducted at LAMPF with LSND, or liquid scintillation neutrino detector.; An analysis of 1994 data found 49 beam-on and 507 beam-off events consistent with oscillation events with a background of 5.1 events and a duty factor of 0.0807. This results in a signal of {dollar}3.0pm7.1sb{lcub}stat{rcub}pm4.0sb{lcub}sys{rcub}.{dollar} The resulting exclusion limits do not exclude any new phase space and exclude parts of the inclusion limits from a {dollar}overline{lcub}nusbmu{rcub}tooverline{lcub}nusb{lcub}e{rcub}{rcub}{dollar} analysis from LSND.
