Photon neutrino interaction in a charge neutral magnetized medium

In the standard model the null electric charge of neutrinos (ν) are protected by the absence of gauge anomaly. However in the extension of standard model neutrinos can have intrinsic charge but we are not considering the same here. We are estimating the induced charge on ν (Dirac neutrino) due to medium effects. As far as their astrophysical application is concern, the rotating dipole field of stars generate an electric field E_∥. The neutrinos can interact with this electric field through their induced charge. Thus screening the same. On the other hand, if this is true then the electric field of bare strange star may get screened by in medium charged neutrinos. There may be other astrophysical or cosmological implications of the same but we do not discuss them here. For an old compact object like hypothetical strange star, these medium induced neutrino charge stands a chance to screen the electric field (E_∥) of the star. We would like to explore some of these issues in future
