TL;DR
This paper introduces a combined effective model that accurately reproduces QCD thermodynamics, capturing the transition between hadronic matter and quark-gluon plasma as seen in lattice QCD simulations.
Contribution
It presents a novel integrated model combining the extended Mott-Hagedorn resonance gas and PNJL model to describe QCD thermodynamics across different phases.
Findings
Model reproduces lattice QCD equation of state
Captures physical characteristics of dense hadronic matter
Includes hadron dissociation via state-dependent resonance widths
Abstract
A combined effective model reproducing the equation of state of hadronic matter as obtained in recent lattice QCD simulations is presented. The model reproduces basic physical characteristics encountered in dense hadronic matter in the quark-gluon plasma (QGP) phase and the lower temperature hadron resonance gas phase. The hadronic phase is described by means of an extended Mott-Hagedorn resonance gas while the QGP phase is described by the extended PNJL model. The dissociation of hadrons is obtained by including the state dependent hadron resonance width.
