Nuclear matter properties in the non-linear Walecka model at finite temperature with interaction between the σ - ω mesons

Abstract

In this work in contrast to the usual Walecka model [1] we include the interaction between the σ – ω 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 μ and baryon density ρN.
