Neutrino dispersion in a charge-symmetric plasma

The influence of a charge-symmetric magnetized plasma on the neutrino dispersion is investigated. A general expression is derived for the contribution of a magnetized plasma to the additional neutrino energy. The physical conditions of weakly, moderately, and strongly magnetized plasmas are considered in detail. The result for the additional neutrino energy in the case of intermediate fields is shown to differ significantly from the results presented in the literature previously.
