Preliminary results of nu/sub e/e/sup -/ scattering at LAMPF
We present preliminary results of a neutrino experiment in progress at LAMPF by an Irvine-Los Alamos-Maryland collaboration. We have observed a signal consistent with nu/sub e/e/sup -/ elastic scattering, with a 15-ton sandwich detector. The number of these nu/sub e/e/sup -/ candidates agrees with that predicted by the Weinberg-Salam electroweak theory. The corresponding sin/sup 2/theta/sub w/ and total cross section are reported. This study shows that the interference of weak charged-current and weak neutral-current in nu/sub e/e/sup -/ scattering is not constructive. We also searched for anomalous appearance of anti nu/sub e/ from the LAMPF beam stop. An upper limit for the multiplicative lepton number conservation law, and limits for anti nu/sub ..mu../ ..-->.. anti nu/sub e/ oscillation are given. 15 references.
