It has been widely used to describe resonances in hadronic physics, combined with chiral perturbation theory, as well as in the strongly interacting symmetry breaking sector. In this work we show how it can be slightly modified to also account for the subthreshold region, incorporating correctly the Adler zeros required by chiral symmetry and eliminating spurious poles. These improvements produce negligible effects on the physical region.engjournal articlehttp://dx.doi.org/10.1103/PhysRevD.77.056006http://journals.aps.orgopen access51-73Chiral perturbation-theorySymmetry-breaking sectorEquivalence theoremHiggs bosonsOne-loopScatteringLagrangiansModelMassπFísica-Modelos matemáticosFísica matemática
