Abstract
We perform a Dalitz plot analysis of the decay with the CLEO-c data set of of collisions accumulated at . This corresponds to about 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 contribution. We measure the magnitude, phase, and fit fraction of , , , , , and contributions and limit the possible contributions of other and resonances that could appear in this decay.
