摘要：

An amplitude analysis of the D+, D-s(+) --> 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 Gamma(D+-->pi(-)pi(+)pi(+))/Gamma(D+-->K(-)pi(+)pi(+)) and Gamma(D-s(+)-->pi(-)pi(+)pi(+))/Gamma(D-s(+)-->K(-)K(+)pi(+)). (C) 1997 Published by Elsevier Science B.V.
