Casimir scaling hypothesis on the nonperturbative force in QCD vs. dual superconducting scenario of confinement

Abstract

We discuss the Casimir scaling hypothesis on the nonperturbative force in terms of the dual superconducting picture of the QCD vacuum by calculating the string tensions of flux tubes associated with static charges in various SU(3) representations in the dual Ginzburg-Landau (DGL) theory.
