Neutrino‐electron elastic scattering was observed at LAMPF with a 15‐ton fine‐grained tracking calorimeter exposed to electron‐neutrinos from muon decay at rest. The measured νee−→νee− elastic scattering cross section, 10.0±1.5(stat)±0.09(syst)×10−45 cm−2×(Eν(MeV)), gives a model independent measurement of the strength of the destructive interference between the charged and neutral currents, I=−1.07±0.21, that agrees well with the standard model (SM) prediction I=−1.08. The agreement between the measured electroweak parameters and SM expectations is used to place limits on neutrino properties, such as neutrino flavor‐changing neutral currents and neutrino electromagnetic moments, and on the masses of hypothetical new bosons that would interact with leptons. |
