| dc.description | We report on a search for the CP asymmetry in the singly Cabibbo-suppressed decays D+ -> KKpi and in the resonant decays D+ -> phipi and D+ -> KstarK based on a data sample of 79.9 fb^-1 recorded by the BABAR detector. We use the Cabibbo-favored Ds -> KKpi branching fraction as normalization in the measurements to reduce systematic uncertainties. The CP asymmetries obtained are A_{CP}(KKpi) = (1.4 +/- 1.0 (stat.) +/- 0.8 (syst.) x 10^-2, A_{CP}(phi pi) = (0.2 +/- 1.5 (stat.) +/- 0.6 (syst.) x 10^-2, and A_{CP}(Kstar K) = (0.9 +/- 1.7 (stat.) +/- 0.7 (syst.) x 10^-2. The relative branching fraction Gamma(D+ -> KKpi)/Gamma(D+ -> Kpipi) is also measured and is found to be (10.7 +/- 0.1 (stat.) +/- 0.2 (syst.) x 10^-2. | |
