Abstract: The idea that the dual gauge symmetry of nontrivial type (i.e., non-Abelian)
is a new manifestation of the global flavor symmetry, seems to be gaining familiarity, if not yet properly understood. The main issue is the subtle interplay between the strong gauge dynamics involving various soliton-like excitations and the global symmetry.
We discuss, in an attempt to go into the heart of the problem, monopole-vortex complex solitonlike configurations arising in hierarchically broken gauge systems, G ➞ H ➞ 1, taking as a concrete model the softly-broken N=2 supersymmetric Quantum Chromodynamics. Our consideration involves also the rich results on the non-Abelian-vortex moduli obtained in the last few years, as well as some old and more recent results about non-Abelian monopoles. There is in fact a clear indication how the dual gauge symmetry arises from flavor in the r-vacua of the softly-broken N=2 susy QCD. If realized in the real world QCD, this kind of mechanism would explain why the chiral symmetry breaking and confinement appear to be interlocked.
