Resonance spectrum of the strongly interacting symmetry-breaking sector
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 h...

| Sumario: | 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. |
