Such interactions affect the propagation of neutrinos through a magnetized plasma. We investigate the neutrino-photon absorptive processes, at the one-loop level, for massless neutrinos in a weakly magnetized plasma. We find that there is no correction to the absorptive part of the axial-vector–vector amplitude due to the presence of a magnetic field to the linear order in the field strength.enMagnetic fieldMediumNeutrino propagationArticle
