SEMINAR: Dispersive model connecting light scalar meson poles with their Regge trajectories

Friday July 12 2013, 2:30pm - Seminar room

Speaker: Jenifer Nebreda (Yukawa Institute for Theoretical Physics)

Abstract:
Our preliminary results on the study of the connexion between light meson poles and their Regge trajectories will be presented.

Our aim is to obtain the slope of the trajectories where the rho and sigma mesons lie. For that, we make a parametrization of the amplitudes attending to Regge theory constraints and we fit it so that it reproduces the right position and residue of the resonance poles.
