The chiral and deconfinement phase transitions

TL;DR

This paper explores the relationship between chiral and deconfinement phase transitions in QCD, proposing new order parameters and a dynamical gluodynamic model to better understand the phase diagram at finite temperature and density.

Contribution

It introduces the dressed Polyakov loop as a novel order parameter and develops a dynamical gluodynamic model to describe deconfinement and confinement phenomena.

Findings

The dressed Polyakov loop effectively signals deconfinement transition.

The gluodynamic model captures both electric deconfinement and magnetic confinement.

Proposes a comprehensive QCD phase diagram at finite temperature and density.

Abstract

By introducing the dressed Polayakov loop or dual chiral condensate as a candidate order parameter to describe the deconfinement phase transition for light flavors, we discuss the interplay between the chiral and deconfinement phase transitions, and propose the possible QCD phase diagram at finite temperature and density. We also introduce a dynamical gluodynamic model with dimension-2 gluon condensate, which can describe the color electric deconfinement as well as color magnetic confinement.
