2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/40703I give a brief review of some of the opportunities and challenges that could arise in our quest to unravel the Higgs sector that very probably underlies electroweak symmetry breaking. In particular, I review scenarios with an extended Higgs sector that allow for a heavy SM-like Higgs boson and/or make discovery more difficult while at the same time maintaining consistency with current limits and precision electroweak constraints.26 pages, 9 figures; based on presentations at RADCOR--2000 and PASCOS--2001High Energy Physics - Phenomenologytext
