Findings

Nonextensive effects alter phase transition behavior.

Dependence between nonextensive parameter and coupling constants.

Numerical relation for thermodynamical dependence.

Abstract

We investigate nonextensive effects on phase transition in nuclear matter in the context Walecka many-body field theory. Changes in the general behavior are observed when the results calculated for the nuclear matter at vanishing baryon density are compared to those obtained through the standard Fermi-Dirac distribution. It is observed a dependence between the nonextensive parameter $q$ and the coupling constants $C_S^2$ of the phase transition. A numerical relation for this thermodynamical dependence is also proposed.
