# Quark matter revisited with non extensive MIT bag model

## TL;DR

This paper explores the impact of non-extensive Tsallis statistics on the MIT bag model for quark matter, analyzing phase transitions and stellar properties, revealing notable effects on the phase diagram but minimal impact on star characteristics.

## Contribution

It introduces the application of Tsallis non-extensive statistics to the MIT bag model, providing new insights into quark matter behavior and phase transitions.

## Key findings

- Tsallis statistics significantly alter the QCD phase diagram.
- Minimal effects of Tsallis statistics on quark star macroscopic properties.
- The phase transition analysis shows notable differences with non-extensive statistics.

## Abstract

In this work we revisit the MIT bag model to describe quark matter within both the usual Fermi-Dirac and the Tsallis statistics. We verify the effects of the non-additivity of the latter by analysing two different pictures: the first order phase transition of the QCD phase diagram and stellar matter properties. While, the QCD phase diagram is visually affected by the Tsallis statistics, the resulting effects on quark star macroscopic properties are barely noticed.
