Flavor oscillations of low energy neutrinos in the rotating neutron star

Abstract

We study flavor oscillations of low energy neutrinos propagating in dense matter of a rotating neutron star. On the basis of the exact solutions of the wave equations for neutrinos mass eigenstates we derive the transition probability for neutrinos having big initial angular momentum. It is found that flavor oscillations of neutrinos with energies of several electron-Volts can be resonancely enhanced.Comment: 3 pages, 1 eps figure, 14lomcon style file is included; submitted to the proceedings of the 14th Lomonosov Conference on Elementary Particle Physic
