摘要：
In this work the neutral-current scattering cross-section for neutrinos on electrons is calculated assuming that a massive Dirac neutrino is characterized by a phenomenological parameters, a charge radius < r(2)> and the right-handed currents are present in the framework of a Left-Right symmetric model (LR). Using the CHARM II result for the charge radius of the muon-neutrino vertical bar < r(2)>vertical bar 6.0 x 10(-33) cm(2), we place a bound on -7.9 x 10(-33) cm(2) <= < r(2)>(LR) <= 7.9 x 10(-33) cm(2). We discuss the relationship between the electron neutral couplings g(V)(nu e) and g(A)(nu e) and the LR model parameters.
