Reinhard Alkofer, Mario Mitter, and Bernd-Jochen Schaefer
TL;DR
This paper reviews functional approaches to QCD, focusing on Green's functions at finite temperature and density, and explores their implications for confinement, chiral symmetry breaking, and color superconductivity.
Contribution
It provides a comprehensive overview of how QCD Green's functions reflect phase transitions and presents new numerical results linking confinement and chiral symmetry.
Findings
Infrared behavior of gluon propagator indicates deconfinement transition
Numerical results confirm the link between confinement and chiral symmetry breaking
Dyson-Schwinger equations suggest properties of color-superconducting phases
Abstract
After presenting a brief summary of functional approaches to QCD at vanishing temperatures and densities the application of QCD Green's functions at non-vanishing temperature and vanishing density is discussed. It is pointed out in which way the infrared behavior of the gluon propagator reflects the (de-)confinement transition. Numerical results for the quark propagator are given thereby verifying the relation between (de-)confinement and dynamical chiral symmetry breaking (restoration). Last but not least some results of Dyson-Schwinger equations for the color-superconducting phase at large densities are shown.
