Studies of Neutrino-Electron Scattering at the Kuo-Sheng Reactor Neutrino Laboratory
Abstract
Studies on electron antineutrino-electron elastic scattering were performed using a 200-kg CsI(Tl) scintillating crystal detector array at the Kuo-Sheng Nuclear Power Plant in Taiwan. The measured cross section of R(exp) = [1.00 +- 0.32(stat)]xR(SM) is consistent with the Standard Model expectation and the corresponding weak mixing angle derived is sin2T = 0.24 +- 0.05 (stat). The results are consistent with a destructive interference effect between neutral and charged-currents in this process. Limits on neutrino magnetic moment of mu(nu(e)) < 2.0 x 10(-10) mu(B) at 90% confidence level and on electron antineutrino charge radius of r(2) < (0.12 +- 2.07)x10(-32) cm2 were also derived.
