Popis:	The purpose of this paper is to study the bulk properties of nucleon-antinucleon plasma as a function of temperature in the relativistic Hartree approximation which takes into account the contribution of vacuum-fluctuation energy using both Walecka's model and the chirally symmetric sigma model. This paper is an extension of previous work of Theis et al. based on Walecka's model and carried out in the mean-field-theory approximation. In our calculation the effective nucleon mass M( can be both greater and less than the free-nucleon mass M. When we consider the M(M branch of the solution is less than that of the M(
