• 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 ⟨r2⟩ 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 |⟨r2⟩| < 6.0 × 10−33 cm2, we place a bound on −7.9 × 10−33 cm2 ≤ ⟨r2⟩LR ≤ 7.9 × 10−33 cm2. We discuss the relationship between the electron neutral couplings gveV and gveA and the LR model parameters.
