- Abstract
The ratios between the string tensions σD of color-electric flux tubes in higher and fundamental SU(3) representations, dD σD /σ3, are systematically studied in a Weyl symmetric formulation of the DGL theory. The ratio is found to depend on the Ginzburg-Landau (GL) parameter, κ ... mx/mB, the mass ratio between the monopoles (mx) and the masses of the dual gauge bosons (mB). While the ratios dD follow a simple flux counting rule in the Bogomol'nyi limit, κ 1.0, systematic deviations appear with increasing κ due to interactions between the fundamental flux inside a higher representation flux tube. We find that in a type-Il dual superconducting vacuum near κ 3.0 this leads to a consistent description of the ratios dD as observed in lattice QCD simulations.
