The confined and Higgs phases are separated by a well-defined phase boundary, marked by proliferating vortices. It is shown that the confinement mechanism at work is precisely the dual superconductor scenario.6 pages, 2 figures, Talk presented at Lattice 2005 (Spin and Higgs Models)High Energy Physics - Latticetext
