Dalitz plot analysis of Ds+→K+K-π+

We perform a Dalitz plot analysis of the decay D-s(+)-> K+K-pi(+) with the CLEO-c data set of 586 pb(-1) of e(+)e(-) collisions accumulated at root s=4.17 GeV. This corresponds to about 0.57x10(6) (DsDs*-/+)-D-+/- pairs from which we select 14 400 candidates with a background of roughly 15%. In contrast to previous measurements we find good agreement with our data only by including an additional f(0)(1370)pi(+) contribution. We measure the magnitude, phase, and fit fraction of K-*(892)K-0(+), phi(1020)pi(+), K-0(*)(1430)K+, f(0)(980)pi(+), f(0)(1710)pi(+), and f(0)(1370)pi(+) contributions and limit the possible contributions of other KK and K pi resonances that could appear in this decay.
