Confinement order parameters in QCD: a view from Schwinger–Dyson equations and related low energy QCD models
Year: 2026
Type: article
Abstract: Confinement and dynamical chiral symmetry breaking are two emergent non-perturbative phenomena of quantum chromodynamics (QCD) that are responsible for the nature of hadron spectra. While it is well known that the chiral condensate is an order parameter for the chiral transition, the Polyakov loop is the associated approximate order parameter for the confinement–deconfinement transition in the pure gauge sector with center symmetry. Nevertheless, this quantity cannot be derived from functional methods, and other quantities have therefore been proposed as order parameters for this transition. In the current investigation, we review and compare several proposed parameters that have been used to describe the confinement/deconfinement transition in QCD and related quantum field theories in the framework of Schwinger–Dyson equations.
