Abstract

A set of selfconsistent Schwinger-Dyson equations for the Walecka model is derived within the framework of the Cornwall-Jackiw-Tomboulis formalism. In the Hartree approximation these equations are solved by propagators with T- and μ-dependent masses. The results are compared to tree-level calculations. The difference is most pronounced for the mass of the scalar meson.
