If new resonances of the electroweak symmetry breaking sector(longitudinal-gauge and Higgs) bosons are found in the 1-3 TeV region, theright tool to assess their properties and confront experimental data in alargely model-independent yet simple manner is Unitarized Effective Theory. Itsingredients are: 1) custodial symmetry and the Equivalence Theorem, that allowto approximate W_L and Z_L by an isospin-triplet of Goldstone bosons omega^a inthe 1-TeV region. 2) The effective coupling of a generic, approximatelymassless scalar-isoscalar h to those Goldstone bosons, and the chiralLagrangian describing them, valid up to about 3 TeV. 3) The Inverse Amplitudeor other unitarization techniques that allow to extend the reach ofperturbation theory to the first resonance in each partial wave. We highlightsome of the parameter space that can give rise to 2-TeV resonances, for examplea simultaneous scalar-isoscalar and a vector-isovector ones (motivated by theATLAS excess) and also the potential importance of coupled-channel dynamicsbetween hh and omega omega.
