摘要
Abstract In the present paper we develop the quantum theory of neutrino spin and spin-flavour oscillations in moving magnetized matter with a special focus on the effects of matter polarization. We derive an effective neutrino evolution Hamiltonian and corresponding expressions for the neutrino oscillation probabilities. Both the case of Dirac and Majorana neutrinos are considered. From the comparison of the neutrino spin oscillation probabilities in the transversally moving matter for the Dirac and Majorana neutrinos it follows that the oscillation patterns is different for theses two cases. In particular, the conditions for the resonances in these two cases are realized at different densities of matter.
