| Popis: | Considering cold, dense quark matter with two massless quark flavors, we demonstrate how, in a self-consistent calculation in the framework of QCD, the condensation of Cooper pairs induces a non-vanishing background color field. This background color field has precisely the right magnitude to cancel tadpole contributions and thus ensures overall color neutrality of the two-flavor color superconductor. 10 pages, contribution to the proceedings of the Erice school "Heavy-Ion Collisions from Nuclear to Quark Matter" 2003 |
