Propagation and Oscillation of Neutrinos with Magnetic Moment Inside the Sun

Abstract

The VVO mechanism suggests that the existence of a neutrino magnetic moment would lead to variations of the observed solar neutrino flux with the magnetic activity of the sun. The MSW mechanism suggests neutrino oscillations in the dense plasma solar interior. Assuming a non- vanishing neutrino magnetic moment and a magnetic field gradient increasing towards the solar core as required in some dynamo models, the combined effects of the oscillations and the flipping on neutrino propagation in the solar interior is studied. The effects of charge is scattering cross- section is also considered.
