Dalitz plot analysis of D0→K̄0K+K-
A Dalitz plot analysis of approximately 12500 D0 events reconstructed in the hadronic decay D0→K̄0K+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...

| description | A Dalitz plot analysis of approximately 12500 D0 events reconstructed in the hadronic decay D0→K̄0K+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 Υ(4S) resonance. The events are selected from e+e-→cc̄ annihilations using the decay D*+→D0π+. The following ratio of branching fractions has been obtained: BR= Γ(D0→K̄0K+K-)Γ(D0→K̄0π+π-)=(15.8±0. 1(stat.)±0.5(syst.))×10-2. Estimates of fractions and phases for resonant and nonresonant contributions to the Dalitz plot are also presented. The a0(980)→K̄K projection has been extracted with little background. A search for CP asymmetries on the Dalitz plot has been performed. © 2005 The American Physical Society. |
