Electromagnetic structure of the massive, Dirac neutrinos

Abstract

All the electromagnetic formfactors for the massive, Dirac neutrinos are calculated in the frame o f the GSW model. Their dependence on the Kobayashi-Maskawa mixing and C, P, T properties are discussed. Three formfactors depend on gauge, the other ones are gauge independent. In the static limit q2 -* 0, in one loop approximation the Dirac neutrino has two electromagnetic characteristics— the magnetic moment (which vanishes for massless neutrino) and anapole (which is different from zero in the massless limit). Present experimental data do not give possibility to check these static properties o f the neutrinos[…]
