Abstract
We present measurements of branching fractions and CP-violating asymmetries in B-0-->rho(+/-)pi(-/+) and B-0-->rho(-)K(+) decays. The results are obtained from 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. From a time-dependent maximum likelihood fit we measure the branching fractions B(B-0-->rho(+/-)pi(-/+))=[22.6+/-1.8 (stat)+/-2.2 (syst)]x10(-6) and B(B-0-->rho(-)K(+))=(7.3 (-1.2) (+1.3)+/-1.3)x10(-6), and the CP-violating charge asymmetries A(CP)(rhopi)=-0.18+/-0.08+/-0.03 and A(CP)(rhoK)=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.
