Abstract
An amplitude analysis of the D+, Ds+ → pi−pi+pi+ Dalitz plots is presented using data collected by the Fermilab high-energy photoproduction experiment E687. The data are fitted to a model consisting of a sum of relativistic Breit-Wigner amplitudes for the intermediate two-body resonant decay modes plus a flat non-resonant contribution. From the fit we derive decay fractions and relative phases. We also present measurements of G(D+->pi-pi+pi+)/G(D+->K-pi+pi+)and G(D(s)+->pi-pi+pi+)/G(D(s)+->K-K+pi+)
