摘要: We investigate the phases of dense QCD matter at finite temperature with Dyson-Schwinger equations for quark propagator N f = 2 + 1 flavors. For gluon we take a fit to quenched lattice data and add quark-loop effects perturbatively in hard-thermal-loop-hard-dense-loop approximation. consider 2SC CFL-like pairing chiral up down quarks massive strange present results condensates phase diagram. find dominant CFL chemical potentials larger than 500-600MeV. At lower values potential phase, which also exists small band higher temperatures potentials. With 20–30 MeV, critical normal turn out be quite small.
