[en] In the framework of the Weinberg-Salam theory the processes ν(ν tilde)+P→ν(ν tilde)+P are considered. Their cross sections have been calculated by using nucleon form factors compatible with the data obtained. It is shown that at neutrino (antineutrino) energy < or approximately 1 GeV the uncertainties of the form factors slightly affect the cross sections of elastic ν(ν tilde) N scattering. The cross section of the process ν tilde +p→ν tilde+P depends strongly on the parameter sinsup(2)THETAsub(W) for q² near qsub(max)sup(2)
