Astrophysical neutrino oscillations accounting for neutrino charge radii

Abstract

We derive for the first time an effective neutrino evolution Hamiltonian accounting for neutrino interactions with external magnetic field due to neutrino charge radii and anapole moment. The results are interesting for possible applications in astrophysics.
