| 英文摘要 | We report on a search for the CP asymmetry in the singly Cabibbo-suppressed decays D+-> K(-)K(+)pi(+) and in the resonant decays D+->phi pi(+) and D+->(K) over bar K-*0(+) based on a data sample of 79.9 fb(-1) recorded by the BABAR detector. We use the Cabibbo-favored D-s(+)-> K(-)K(+)pi(+) branching fraction as normalization in the measurements to reduce systematic uncertainties. The CP asymmetries obtained are A(CP)(K-K+ pi(+/-)) = (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)((K) over bar K-*0(+/-))=(0.9 +/- 1.7(stat) +/- 0.7(syst)) x 10(-2). The relative branching fraction Gamma(D+-> K(-)K(+)pi(+))/Gamma(D+ -> K(-)pi(+)pi(+)) is also measured and is found to be (10.7 +/- 0.1(stat) +/- 0.2(syst)) x 10(-2). |
