Abstract
Finite-temperature and -density radiative corrections to orderα to the charged-current MSW process are considered in the real-time version of thermal field theory. We confirm the absence of infrared and electron mass singularities in the real part of thev e self-energy, calculated in a background of electrons at finite chemical potential. As a consequence, this indicates that at orderα the perturbation series with respect to electromagnetic interactions is adequate for a coherent process.
