What Is Confinement?

Abstract

Confinement and symmetry. Linear Regge trajectories, the linear static quark potential, and the “spinning stick” model. String breaking, existence of “color confinement” in the Higgs phase, and the difficulty of associating confinement with an unbroken or spontaneously broken remnant gauge symmetry. Confinement as magnetic disorder; center symmetry as the global symmetry corresponding to the confined phase.
