Constituent Quarks and Gluons, Polyakov loop and the Hadron Resonance Gas Model

TL;DR

This paper explores the representation of the Polyakov loop within the hadron resonance gas model using a Polyakov-constituent quark framework, incorporating quantum effects and discussing exotic states.

Contribution

It introduces a detailed Polyakov-constituent quark model that accounts for quantum and local properties of the Polyakov loop, extending previous first-principles arguments.

Findings

Polyakov loop can be modeled within the hadron resonance gas framework.

Quantum and local features of the Polyakov loop are incorporated.

Exotic states in the spectrum are discussed.

Abstract

Based on first principle QCD arguments, it has been argued in arXiv:1204.2424[hep-ph] that the vacuum expectation value of the Polyakov loop can be represented in the hadron resonance gas model. We study this within the Polyakov-constituent quark model by implementing the quantum and local nature of the Polyakov loop hep-ph/0412308, hep-ph/0607338. The existence of exotic states in the spectrum is discussed.
