| 英文摘要 | Branching fraction measurements using B-meson decays to K(S)(0)pi(+)pi(-) are presented. These measurements were obtained by analyzing a data sample of 88.9x10(6) Y(4S)-->B (B) over bar decays collected with the BABAR detector at the SLAC PEP-II asymmetric-energy B factory. Using a maximum likelihood fit, the following branching fraction results were obtained: B(B-0-->K(0)pi(+)pi(-))=(43.7+/-3.8+/-3.4)x10(-6), B(B-0-->K(*+)pi(-))=(12.9+/-2.4+/-1.4)x10(-6), and B(B-0-->D-(-->K(S)(0)pi(-))pi(+))=(42.7+/-2.1+/-2.2)x10(-6). The CP violating charge asymmetry A(K)(*)pi for the decay B-0-->K(*+)pi(-) was measured to be A(K)(*)pi=0.23+/-0.18(-0.06)(+0.09). For all these measurements the first error is statistical and the second is systematic. |
