SUMMARY:Dispersive study of pion-kaon scattering: the kappa and other strange resonances and threshold parameters
DESCRIPTION:We have recently completed the coupled dispersive analysis of  pi pi -> K anti-K We show that just fitting data fails to satisfy the dispersive representation and leads to inconsistencies with threshold sum-rules as well as unreliable resonance parameterizations. Our main result is a set of constrained fits to data that satisfy 16 dispersion relations of different kinds and allow for a reliable extraction of threshold and subtreshold parameters to be compared with Chiral Perturbation Theory and lattice QCD. In addition\, we obtain a precise dispersive determination of the controversial light kappa-meson parameters\, which has therefore become a “confirmed” state in the PDG\, completing the light meson scalar nonet. The constrained fits to data are easy to implement and ready for further theoretical and experimental studies. \nLa riunione sarà effettuata in modalità telematica\, tramite collegamento Webex\, seguendo le istruzioni riportate.
