From Chiral quark dynamics with Polyakov loop to the hadron resonance gas model

TL;DR

This paper explores how chiral quark models incorporating the Polyakov loop transition into a hadron resonance gas, emphasizing the quantum and local properties of the Polyakov loop at finite temperature.

Contribution

It demonstrates the mechanism by which the phase transition from chiral quark models to the hadron resonance gas occurs, highlighting the role of the Polyakov loop's quantum and local characteristics.

Findings

Transition to hadron resonance gas is driven by Polyakov loop properties.

Quantum and local nature of the Polyakov loop are crucial for the transition.

Provides a framework connecting chiral quark models to hadron gas description.

Abstract

Chiral quark models with Polyakov loop at finite temperature have been often used to describe the phase transition. We show how the transition to a hadron resonance gas is realized based on the quantum and local nature of the Polyakov loop.
