摘要：

In this work in contrast to the usual Walecka model [1] we include the interaction between the sigma - omega mesons [2,3] with the aim of studying the nuclear matter properties in the relativistic mean-field theory in the regime of high temperatures. Therefore in our work we use the non-linear Walecka model. We investigate whether the phase transition characteristic of other models without these interactions vanishes for a given value of chemical potential mu and baryon density rho(N).
