| ABSTRACT | We calculate the finite temperature self-energy for neutrinos in the presence of a constant magnetic field in a medium in the unbroken SU(2) x U(1) model, We obtain the exact dispersion relation for such neutrinos and find that the thermal effective mass is modified by the magnetic field, We also find a simple analytic expression for the dispersion relation and obtain the index of refraction for large neutrino momentum.
