NJL-model description of Goldstone boson condensation in the color-flavor locked phase
arXiv:hep-ph/0410397 · doi:10.1016/j.physletb.2005.01.027
Abstract
A schematic NJL-type model is employed to investigate kaon and pion condensation in deconfined quark matter in the color-flavor locked (CFL) phase, explicitly referring to quark degrees of freedom. To that end we allow for non-vanishing pseudoscalar diquark condensates in addition to the scalar ones which constitute the CFL phase. Color neutrality is ensured by the appropriate choice of color chemical potentials. The dependence of the free energy in the Goldstone condensed phases on quark masses and charge chemical potentials is found to be in good qualitative -- in most cases also quantitative -- agreement with the predictions obtained within the effective Lagrangian approach.
