Аннотация:Using a modification of the Standard Model, which makes it possible to construct the Fock spacefor flavor neutrinos, we show that, when a neutrino interacts with a constant electromagnetic field and withmatter characterized by constant velocity and polarization, extra T-violating terms arise in the spin-flavortransition probabilities. In a simple model, which takes into account only interaction due to neutral currentsand diagonal neutrino magnetic moments, CPT symmetry is restored if we perform the symmetry transformationsboth for neutrino and matter components in the presence of the same electromagnetic field.
