Neutrino oscillations in astrophysical environment accounting for neutrino charge radius and anapole moment

Abstract

We derive an effective neutrino evolution Hamiltonian and corresponding expression for neutrino spin oscillations probabilities accounting for neutrino interactions with external electric current due to neutrino charge radii and anapole moment. The results are interesting for possible applications in astrophysics.
