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