Longitudinal gluons and Nambu-Goldstone bosons in a two-flavor color superconductor

Abstract

In a two-flavor color superconductor, the SU(3)c gauge symmetry is spontaneously broken by diquark condensation. The Nambu-Goldstone excitations of the diquark condensate mix with the gluons associated with the broken generators of the original gauge group. It is shown how one can decouple these modes with a particular choice of ’t Hooft gauge. We then… (More)
