An amplitude analysis of the D+, D+s → π-π+π+ 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 Γ(D+ →π-π+π+)/Γ(D+ →K-π+π+) and Γ(D+ →π-π+π+)/Γ(D +s →K-K+π+).

Abstract

An amplitude analysis of the D+, D+s → π-π+π+ 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 Γ(D+ →π-π+π+)/Γ(D+ →K-π+π+) and Γ(D+ →π-π+π+)/Γ(D +s →K-K+π+).
