Abstract

Amplitude analyses of the D+ and Ds+ → K+K−pi+ Dalitz plots are presented using data collected by the Fermilab high energy photoproduction experiment E687. Our data are fit to a model consisting of a sum of Breit-Wigner amplitudes for the intermediate two-body resonant decay modes. We extract decay fractions and relative phases. These results are used to infer new branching ratios for D+ → K+K−pi+ inclusive as well as the phi pi+ and anti(K)*0(892)K+ channels.
