摘要：

We present a study of B--->(DCPK-)-K-0 decays, where D-CP(0) is reconstructed in CP-even channels, based on a sample of 88.8x10(6) Y(4S)-->B (B) over bar decays collected with the BABAR detector at the PEP-II e(+)e(-) storage ring. We measure the ratio of Cabibbo-suppressed to Cabibbo-favored branching fractions B(B--->(DCPK-)-K-0)/B(B--->D(CP)(0)pi(-))=[8.8+/-1.6(stat)+/-0.5(syst)]x10(-2) and the CP asymmetry A(CP)=0.07+/-0.17(stat)+/-0.06(syst). We also measure B(B--->(DK-)-K-0)/B(B--->D(0)pi(-))=[8.31+/-0.35(stat)+/-0.20(syst)]x10(-2) using a sample of 61.0x10(6) B (B) over bar pairs.
