Abstract
In this talk, the D0 weak decay into KS0 and a scalar resonance, f0(500), f0(980), a0(980), is presented. This decay allows us to produce the three resonances in the same decay in a process that is Cabibbo allowed, hence the rates obtained are large. There is no isospin conservation in the weak decays, hence it offers a unique opportunity to test the ideas of the chiral unitary approach where these resonances are produced from the interaction of pairs of pseudoscalar mesons.
