Abstract
An amplitude analysis of the D+, D-s(+) --> pi(-)pi(+)pi(+) Dalitz plo ts is presented using data collected by the Fermilab high-energy photo production 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. F rom the fit we derive decay fractions and relative phases. We also pre sent measurements of a(D+-->pi(-)pi(+)pi(+))/Gamma(D+-->K(-)pi(+)pi(+) ) and -->pi(-)pi(+)pi(+))/Gamma(D-s(+)-->K(-)K(+)pi(+)). (C) 1997 Publ ished by Elsevier Science B.V.
