Nonabelian Confinement near Nontrivial Conformal Vacua

TL;DR

This paper explores nonabelian confinement and symmetry breaking in supersymmetric theories with nontrivial vacua, highlighting monopole composites' role and implications for understanding QCD ground states.

Contribution

It reveals how monopole composites drive confinement in nonabelian vacua and discusses constraints on infrared degrees of freedom in supersymmetric theories.

Findings

Confinement arises from monopole composites rather than single monopoles.

Strong constraints exist on the types of monopoles that can appear as IR degrees of freedom.

Analogies suggest possible insights into the QCD ground state.

Abstract

We discuss some aspects of confinement and dynamical symmetry breaking in the so-called nonabelian Argyres-Douglas vacua, which occur very generally in supersymmetric theories. These systems are characterized by strongly-coupled nonabelian monopoles and dyons; confinement and dynamical symmetry breaking are caused by the condensation of monopole composites, rather than by condensation of single weakly-coupled monopoles. In general, there are strong constraints on which kind of monopoles can appear as the infrared degrees of freedom, related to the proper realization of the global symmetry of the theory. Drawing analogies to some of the phenomena found here, we make a speculation on the ground state of the standard QCD.
