London model of dual color superconductor

TL;DR

This paper applies a London-like phenomenological model to QCD, proposing a dual color superconductor mechanism that explains confinement and the near-perfect fluidity of quark-gluon plasma.

Contribution

It introduces a non-Abelian London model with a novel chromo-magnetic current term to describe color confinement and plasma behavior in QCD.

Findings

Chromo-electric field exhibits short-range behavior due to the model.

The model links dual superconductivity to quark-gluon plasma fluidity.

Chromo-magnetic currents may have observable effects.

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.
