A simple composite two-Higgs-doublet model is presented. The four-quark interactions arise naturally if there are either extra spatial dimensions or larger gauge symmetries at a multi-TeV scale. Some theoretical and phenomenological implications of these scenarios are discussed.7 pages, revtexHigh Energy Physics - PhenomenologyHigh Energy Physics - Theorytext
