Color-superconductivity within a Dyson-Schwinger approach

Color-superconductivity is usually investigated at asymptotically large densities in a weak coupling expansion and around nuclear saturation density within phenomenological models. To bridge this gap between the weak coupling and the strongly coupled regime, we extend a truncation scheme of Dyson-Schwinger equations, which is in quantitative and qualitative agreement with lattice calculations for the vacuum, to finite densities. We present results for the quasiparticle pairing in different phases, estimate the pressure via the Cornwall-Jackiw-Tomboulis formalism and study the importance of the strange quark mass and neutrality constraints for the color-flavor unlocking.
