2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/140251We give a brief review of recent developments in non-supersymmetric models for electroweak symmetry breaking, including little Higgs, composite Higgs and Higgsless theories. The new ideas such as extra dimensions, AdS/CFT correspondence, dimension-deconstruction, and collective symmetry breaking provide us new tools to construct new models. They also allow some old ideas to be revived and implemented in these new models.Submitted for the SUSY07 proceedings, 8 pagesHigh Energy Physics - Phenomenologytext
