Quark-antiquark potentials from a scalar field in SU(2) YM

Abstract

A generalized Dick model with a potential term is discussed. The solution originating from a static, pointlike, color source is found to have a confining part. The comparison with a wide spectrum of phenomenological quark-antiquark potentials is presented.
