Pseudoscalar condensates in color superconductors — •Hannes Basler and Michael Buballa — Institut für Kernphysik, TU Darmstadt

At sufficiently high densities and low temperatures quark matter forms a color superconductor. In addition to the well-investigated scalar condensates the formation of pseudoscalar condensates has a relevant effect on the structure of a color superconductor. In particular in the color-flavor locked (CFL) phase these pseudoscalar condensates have a significant effect related to the breaking of chiral symmetry and the appearance of Goldstone modes.

We examine such a color superconductor using an NJL model with a self-consistent treatment of the dynamic quark masses. In this framework we calculate the phase diagram for color and electrically neutral quark matter in weak equilibrium.
