## Non-Abelian confinement in N=2 supersymmetric QCD: Duality and kinks on confining strings

Recently we observed a crossover transition (in the Fayet-Iliopoulos parameter) from weak to strong coupling in N=2 supersymmetric QCD with the U(N) gauge group and N{sub f}>N quark flavors. At strong coupling this theory can be described by a dual non-Abelian weakly coupled supersymmetric QCD with the dual gauge group U(N{sub f}-N) and N{sub f} light dyon flavors. Both theories support non-Abelian strings. We continue the study of confinement dynamics in these theories, in particular, metamorphoses of excitation spectra, from a different side. A number of results obtained previously are explained, enhanced and supplemented by analyzing the world-sheet dynamics onmore »
