Analysis of the D+, Ds + → K+K-π+ Dalitz plots

Abstract Amplitude analyses of the D + and D s + → K + K − π + 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 − π + inclusive as well as the Φπ + and K ∗ (892) 0 K + channels.
