Abstract

We perform a Dalitz plot analysis of the decay Ds+→K+K-π+ with the CLEO-c data set of 586pb-1 of e+e- collisions accumulated at s=4.17GeV. This corresponds to about 0.57×106 Ds±Ds* pairs from which we select 14400 candidates with a background of roughly 15%. In contrast to previous measurements we find good agreement with our data only by including an additional f0(1370)π+ contribution. We measure the magnitude, phase, and fit fraction of K*(892)0K+, (1020)π+, K0*(1430)K+, f0(980)π+, f0(1710)π+, and f0(1370)π+ contributions and limit the possible contributions of other KK and Kπ resonances that could appear in this decay.
