Contribution

It provides a detailed analysis of the interplay between chiral and deconfinement transitions in the three-flavor PNJL model, including the role of Polyakov loop dynamics.

Findings

Chiral condensates and quark densities vary with temperature and chemical potential.

Polyakov loop influences the transition from nuclear to quark matter.

The model captures the crossover behavior of deconfinement and chiral symmetry restoration.

Abstract

We study the phase diagram of the three flavor Polyakov-Nambu-Jona Lasinio (PNJL) model and in particular the interplay between chiral symmetry restoration and deconfinement crossover. We compute chiral condensates, quark densities and the Polyakov loop at several values of temperature and chemical potential. Moreover we investigate on the role of the Polyakov loop dynamics in the transition from nuclear matter to quark matter.
