Resumen:
|
We show how the new precise data on kaon decays together with forward dispersion relations, sum rules and once- and twice-subtracted Roy equations allow for a precise analysis of ? ? scattering. The once subtracted Roy equations provide a more stringent consistency check for the parametrizations of the S0- wave data in the region from 450 to 1100 MeV that allows us to present a preliminary determination of the f_0(600) and f_0(980) poles from the constrained dispersive data analysis.
