Abstract
A Dalitz plot analysis of approximately 12 500 D-0 events reconstructed in the hadronic decay D-0->(K) over bar (K+K-)-K-0 is presented. This analysis is based on a data sample of 91.5 fb(-1) collected with the BABAR detector at the PEP-II asymmetric-energy e(+)e(-) storage rings at SLAC running at center-of-mass energies on and 40 MeV below the Upsilon(4S) resonance. The events are selected from e(+)e(-)-> c (c) over bar annihilations using the decay D*+-> D(0)pi(+). The following ratio of branching fractions has been obtained: BR=Gamma(D-0->(K) over bar (K+K-)-K-0)Gamma(D-0->(K) over bar (0)pi(+)pi(-))=(15.8 +/- 0.1(stat.)+/- 0.5(syst.))x10(-2). Estimates of fractions and phases for resonant and nonresonant contributions to the Dalitz plot are also presented. The a(0)(980)->(K) over barK projection has been extracted with little background. A search for CP asymmetries on the Dalitz plot has been performed.
