We present measurements of branching fractions and CP-violating asymmetries in B0-->rho(+/-)pi(-/+) and B0-->rho-K+ decays. The results are obtained from a data sample of 88.9 x 10(6) Upsilon(4S)-->BB decays collected with the BABAR detector at the SLAC PEP-II asymmetric-energy B Factory. From a time-dependent maximum likelihood fit we measure the branching fractions B(B0-->rho(+/-)pi(-/+))=[22.6+/-1.8 (stat)+/-2.2 (syst)]x10(-6) and B(B0-->rho-K+)=(7.3 -1.2( +1.3)+/-1.3)x10(-6), and the CP-violating charge asymmetries A(rhopi)(CP)=-0.18+/-0.08+/-0.03 and A(rhoK)(CP)=0.28+/-0.17+/-0.08, the direct CP violation parameter C(rhopi)=0.36+/-0.18+/-0.04 and the mixing-induced CP violation parameter S(rhopi)=0.19+/-0.24+/-0.03, and the dilution parameters DeltaC(rhopi)=0.28 -0.19( +0.18)+/-0.04 and DeltaS(rhopi)=0.15+/-0.25+/-0.03.
我们给出了(B^0\to\rho^{\pm}\pi^{\mp})和(B^0\to\rho^-K^+)衰变中分支比和CP破坏不对称性的测量结果。这些结果来自于在SLAC PEP-II非对称能量B工厂使用BABAR探测器收集的(88.9\times10^{6})个(\Upsilon(4S)\to BB)衰变的数据样本。通过时间相关的最大似然拟合，我们测量出分支比(B(B^0\to\rho^{\pm}\pi^{\mp})=[22.6\pm1.8)（统计）(\pm2.2)（系统）(\times10^{-6})以及(B(B^0\to\rho^-K^+)=(7.3 -1.2( +1.3)\pm1.3)\times10^{-6})，CP破坏电荷不对称性(A_{\rho\pi}^{CP}=-0.18\pm0.08\pm0.03)和(A_{\rho K}^{CP}=0.28\pm0.17\pm0.08)，直接CP破坏参数(C_{\rho\pi}=0.36\pm0.18\pm0.04)以及混合诱导CP破坏参数(S_{\rho\pi}=0.19\pm0.24\pm0.03)，还有稀释参数(\Delta C_{\rho\pi}=0.28 -0.19( +0.18)\pm0.04)和(\Delta S_{\rho\pi}=0.15\pm0.25\pm0.03)。
