Abstract

The cross section for the elastic scattering reaction νe+e-→νe+e- was measured by the Liquid Scintillator Neutrino Detector using a μ+ decay-at-rest νe beam at the Los Alamos Neutron Science Center. The standard model of electroweak physics predicts a large destructive interference between the charge current and neutral current channels for this reaction. The measured cross section, σνe+e-= [10.1± 1.1(stat) ±1.0(syst)]×Eνe (MeV)× 10-45 cm2, agrees well with standard model expectations. The measured value of the interference parameter, I= -1.01±0.13(stat)±0.12(syst), is in good agreement with the standard model expectation of ISM= -1.09. Limits are placed on neutrino flavor-changing neutral currents. An upper limit on the muon-neutrino magnetic moment of 6.8×10-10μBohr is obtained using the νμ and ν′μ fluxes from π+ and μ+ decay. ©2001 The American Physical Society.
