Nonextensive relativistic nuclear and subnuclear equation of state

TL;DR

This paper explores how nonextensive statistical mechanics, based on Tsallis' framework, influences the relativistic nuclear and subnuclear equations of state, especially during phase transitions relevant to high-energy collisions.

Contribution

It introduces a nonextensive thermodynamic approach to study phase transitions in nuclear matter, extending traditional models with Tsallis' statistics.

Findings

Nonextensive effects modify the equation of state.

Small deviations from standard statistics impact phase transition conditions.

Relevance for interpreting heavy-ion collision experiments.

Abstract

Following the basic prescriptions of the Tsallis' nonextensive relativistic thermodynamics, we investigate the relevance of nonextensive statistical effects on the relativistic nuclear and subnuclear equation of state. In this framework, we study the first order phase transition from hadronic to quark-gluon plasma phase by requiring the Gibbs conditions on the global conservation of the electric and the baryon charges. The relevance of small deviations from the standard extensive statistics is investigated in the context of intermediate and high energy heavy-ion collisions.
