Abstract
We report on recent results on the decay of the phi into pi+ pi- and phi radiative decays into pi0 pi0 gamma and pi0 eta gamma, which require the consideration of the final state interaction of a pair of mesons in a region inaccessible to Chiral Perturbation Theory. By using nonperturbative chiral unitary methods for the meson meson interaction we can obtain the corresponding decay widths and the results are compared with recent experimental data.
