Abstract:
The string tensions of flux tubes associated with static charges in various SU(3) representations are studied within the dual Ginzburg-Landau (DGL) theory. The ratios of the string tensions between higher and fundamental representations, , are found to depend only on the Ginzburg-Landau (GL) parameter, , the mass ratio between monopoles and dual gauge bosons . In the case of the Bogomol'nyi limit (), analytical values of are easily obtained by adopting the manifestly Weyl invariant formulation of the DGL theory, which are provided simply by the number of color-electric Dirac strings inside the flux tube. A numerical investigation of the ratio for various GL-parameter cases is also performed, which suggests that the Casimir scaling is obtained in the type-II parameter range within the interval for various ratios .- gauge field theory: SU(3)
