Generation of massive neutrinos by variable fields with allowance for mixing and radiative effects

The probabilities of the processesF v _i V _j andFB v _i V _j of generation of massive neutrinos by a variable electromagnetic field, due to the contribution of four-particle peaks in the one-loop approximation with allowance for mixing, are obtained. A comparative analysis is made of the quantities considered here and of generation mechanisms discussed earlier (F v _i V _j ) in the case of vacuum neutrino synchrotron emission.Moscow State Pedagogical Institute.
