Nonextensive statistical effects in the quark-gluon plasma formation at relativistic heavy-ion collisions energies

TL;DR

This paper explores how non-extensive statistical mechanics influences the equation of state of hadronic matter and quark-gluon plasma at finite temperature and density, emphasizing the role of strange matter in relativistic heavy-ion collisions.

Contribution

It introduces a non-extensive statistical framework to study the phase transition between hadronic matter and quark-gluon plasma, including strange particles, using extended models.

Findings

Non-extensive effects significantly alter the equation of state.

Strange matter plays a crucial role in the phase transition.

Non-extensive statistics modify particle distributions in the plasma.

Abstract

We investigate the relativistic equation of state of hadronic matter and quark-gluon plasma at finite temperature and baryon density in the framework of the non-extensive statistical mechanics, characterized by power-law quantum distributions. We impose the Gibbs conditions on the global conservation of baryon number, electric charge and strangeness number. For the hadronic phase, we study an extended relativistic mean-field theoretical model with the inclusion of strange particles (hyperons and mesons). For the quark sector, we employ an extended MIT-Bag model. In this context we focus on the relevance of non-extensive effects in the presence of strange matter.
