Abstract

We report on a recent search for [...] appearance from stopped [...] and [...] decay made by the LAMPF experiment E645. The appearance of [...] may occur from [...], [...], or [...] oscillations. Appearance may also occur from rare [...] decay, which is allowed by a multiplicative lepton charge conservation law. The neutrino energies range from [...] to 52.8MeV. The neutrino detector, which is located 26.1 meters from the neutrino source, consists of a segmented liquid scintillator and proportional drift tube central detector surrounded by both active and passive shielding. The central detector detects [...] through the [...] Charge Current (CC) reaction, which is signaled by the direct detection of the final state positron and neutron. The hydrogen-rich liquid scintillators act as free proton targets for the [...] CC reaction. The neutrons are detected through radiative neutron capture on gadolinium. We find no evidence for [...] appearance in the first year of running. New limits on the [...] oscillation parameters and the rare [...] decay branching ratio are presented.
