Abstract

A Dalitz plot analysis of approximately 12500 D0 events reconstructed in the hadronic decay D0âKÌ0K+K- is presented. This analysis is based on a data sample of 91.5fb-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 Î¥(4S) resonance. The events are selected from e+e-âccÌ annihilations using the decay D*+âD0Ï+. The following ratio of branching fractions has been obtained: BR= Î(D0âKÌ0K+K-)Î(D0âKÌ0Ï+Ï-)=(15.8Â±0. 1(stat.)Â±0.5(syst.))Ã10-2. Estimates of fractions and phases for resonant and nonresonant contributions to the Dalitz plot are also presented. The a0(980)âKÌK projection has been extracted with little background. A search for CP asymmetries on the Dalitz plot has been performed. Â© 2005 The American Physical Society.
