London model of dual color superconductor

Abstract

Following closely the logic of the London phenomenological macroscopic theory of the Meissner effect in superconductors we describe the origin of the short-range behavior of the chromo-electric field, the necessary ingredient for color confinement in QCD. The genuinely non-Abelian model is specified by the strong-coupling colored-gluon current. Its first term, as the superconductivity current, is proportional to the gauge potential. The new term is simply related to the chromo-magnetic pseudo-vector current of the non-Abelian Bianchi identity. We suggest that this London dual color superconductivity current is responsible for the observed almost perfect fluidity in droplets of the strongly interacting quark-gluon plasma. Its chromo-magnetic component should have a specific experimental manifestation.
