Static potential from spontaneous breaking of scale symmetry
arXiv:hep-th/0702067 · doi:10.1016/j.physletb.2007.04.011
Abstract
We determine the static potential for a heavy quark-antiquark pair from the spontaneous symmetry breaking of scale invariance in a non-Abelian gauge theory. Our calculation is done within the framework of the gauge-invariant, path-dependent, variables formalism. The result satisfies the 't Hooft basic criterion for achieving confinement.
