Restoration of Chiral Symmetry in Light-Front Finite-Temperature Field Theory

摘要

We investigate the properties of qq and qq states in hot and dense quark matter in the framework of light-front finite-temperature field theory. Presently we use the Nambu-Jona-Lasinio model of QCD and derive the gap equation at finite temperature and density. We study pionic and scalar diquark dynamics in quark matter and calculate the masses and the Mott dissociation as a function of the temperature T and the chemical potential μ. For the scalar diquark we determine the critical temperature of color superconductivity.
