Description

It is believed that the running (for instance, COHERENT) and forthcoming terrestrial neutrino experiments will be sensitive to the neutrino charge radius [1] that is one of the neutrino fundamental electromagnetic characteristics [2] predicted [3] to be non-zero even in the Standard Model. In this work we continue our studies [4] on neutrino oscillations in an environment with large electric currents accounting for the diagonal and non-diagonal neutrino charge radii and anapole moments. We derive neutrino evolution equation in moving matter with electric currents and consider spin and spin-flavor neutrino oscillations. We also study conditions for possible resonances of neutrino oscillations engendered by the neutrino charge radii and compare these conditions with real astrophysical environments.
