Measurement of the Branching Fractions and CP Asymmetry of B[superscript -]→D[subscript (CP)][superscript 0]K[superscript -] Decays with the BABAR Detector
We present a study of B[superscript -]→D[subscript CP][superscript 0]K[superscript -] decays, where D[subscript CP][superscript 0] is reconstructed in CP-even channels, based on a sample of 88.8×10[superscript 6] Υ(4S)→BB̅ decays collected with the BABAR detector at the PEP-II e[superscript +]e[supe...

| description | We present a study of B[superscript -]→D[subscript CP][superscript 0]K[superscript -] decays, where D[subscript CP][superscript 0] is reconstructed in CP-even channels, based on a sample of 88.8×10[superscript 6] Υ(4S)→BB̅ decays collected with the BABAR detector at the PEP-II e[superscript +]e[superscript -] storage ring. We measure the ratio of Cabibbo-suppressed to Cabibbo-favored branching fractions B(B[superscript -]→D[subscript CP][superscript 0]K[superscript -])/B(B[superscript -]→D[subscript CP][superscript 0]π[superscript -])=[8.8±1.6(stat)±0.5(syst)]×10[superscript -2] and the CP asymmetry A[subscript CP]=0.07±0.17(stat)±0.06(syst). We also measure B(B[superscript -]→D[superscript 0]K[superscript -])/B(B[superscript -]→D[superscript 0]π[superscript -])=[8.31±0.35(stat)±0.20(syst)]×10[superscript -2] using a sample of 61.0×10[superscript 6] BB̅ pairs. |
