Identification of non-ordinary mesons from the dispersive connection between their poles and their Regge trajectories: the f0(500) resonance
J. T. Londergan, J. Nebreda, J. R. Pelaez +1
We show how the Regge trajectory of a resonance can be obtained from its pole in a scattering process and analytic constraints in the complex angular momentum plane. The method is…

Present status of light flavoured scalar resonances
J. R. Pelaez
This talk is a brief account of recent developments on light scalar meson spectroscopy. I mostly focus on the major revision of the or meson in the Review of Particl…

Determination of Chiral Perturbarion Theory low energy constants from a precise description of pi-pi scattering threshold parameters
Guillermo Rios, Jenifer Nebreda, Jose R. Pelaez
We report on our determination of the values of the one and two loop low energy constants appearing in the Chiral Perturbation Theory calculation of the pi-pi scattering amplitude.…
