Weak neutral currents and neutrino electromagnetic properties

The phenomenological Hamiltonian for weak lepton interaction that contains, along with a charged current V-A interaction, a neutral current V-A interation and the dispersion method are used to study the effect of lepton and nucleon currents on the electromagnetic properties of the neutrino. Expressions are obtained for the neutrino formfactor F(q²) when it satisfies the dispersion relations without subtraction and with one subtraction.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 5, pp. 43–48, May, 1977.
