I have also greatly appreciated the patience of M. Suzuki during his explanations and discussions on the unphysical poles. I am also indebted to R.S. Chivukula for his comments on models with I52 resonances. This work has been partially supported by the Ministerio de Educación y Ciencia (Spain) (Grant No. CICYT AEN93-0776). Partial support by U.S. DOE under Contract No. DE-AC03-76SF00098 is gratefully acknowledged.Within the chiral Lagrangian formalism it is possible to describe the general strongly coupled symmetry-breaking sector in terms of a few parameters. Based on a dispersive approach we study the resonance spectrum up to 3 TeV in chiral parameter space. This procedure could also be useful to extract higher energy resonant behavior from low-energy collider data. It is also shown how the method reproduces the correct pole structure of resonances as well as other analytic features. The results also hint at a possible excluded region of parameter space.engjournal articlehttp://dx.doi.org/10.1103/PhysRevD.55.4193http://journals.aps.orgopen access51-73Chiral perturbation-theoryEquivalence theoremHiggs-bosonStandard modelHeavy higgsOne-loopScatteringEnergiesMassWsFísica-Modelos matemáticosFísica matemática
