The authors present preliminary measurements of branching fractions and CP-violating charge asymmetries in B-meson decays to[rho][pi]. The data sample comprises 89 million[Upsilon](4S)[yields] B[bar B] decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factor at SLAC. They find the charge-averaged branching fractions[Beta](B[sup+][yields][rho][sup+][pi][sup 0])= (11.0[+-] 1.9(stat.)[+-] 1.9(syst.)) x 10[sup -6] and[Beta](B[sup+][yields][rho][sup 0][pi][sup+])= (9.3[+-] 1.0(stat.)[+-] 0.8(syst.)) x 10[sup -6]; they set a 90% confidence-level upper limit of[Beta](B[sup 0][yields][rho][sup 0][pi][sup 0])

We present measurements of branching fractions and CP-violating asymmetries in B[sup 0][yields][rho][sup[+-]][pi][sup[-+]] and B[sup 0][yields][rho][sup -]K[sup+] decays. The results are obtained from a data sample of 88.9 x 10[sup 6][Upsilon](4S)[yields] B[bar B] decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. From a time-dependent maximum likelihood fit we measure the charge-averaged branching fractions[Beta](B[sup 0][yields][rho][sup[+-]][pi][sup[-+]])= (22.6[+-] 1.8 (stat)[+-] 2.2 (syst)) x 10[sup -6] and[Beta](B[sup 0][yields][rho][sup -]K[sup+])= (7.3[sub -1.2][sup+1.3][+-] 1.3) x 10[sup -6]; and the CP-violating charge asymmetries A[sub CP][sup[rho][pi]]= -0.18[+-] 0.08[+-] 0.03 and A[sub CP][sup[rho]K]= 0.28[+-] 0.17[+-] 0.08; the direct CP violation parameter C[sub[rho][pi]]= 0.36[+-] 0.18[+-] 0.04 and the mixing-induced CP violation parameter S[sub[rho][pi]]= 0.19[+-] 0.24[+-] 0.03; and the dilution parameters[Delta]C[sub[rho][pi]]= 0.28[sub -0.19][sup+0.18][+-] 0.04 and[Delta]S[sub[rho][pi]]= 0.15[+-] 0.25[+-] 0.03.

An improved measurement of the process B{sup {+-}} {yields} {rho}{sup {+-}}{pi}{sup 0} is presented. The data sample of 211 fb{sup -1} comprises 232 million {Upsilon}(4S) {yields} B{bar B} decays collected with the BABAR detector at the PEP-II asymmetric B Factory at SLAC. The yield and CP asymmetry are calculated using an extended maximum likelihood fitting method. The branching fraction and asymmetry are found to be {Beta}(B{sup {+-}} {yields} {rho}{sup {+-}}{pi}{sup 0}) = [10.0 {+-} 1.4 (Stat.) {+-} 0.9 (Syst.)] x 10{sup -6} and {Alpha}{sub CP}(B{sup {+-}} {yields} {rho}{sup {+-}}{pi}{sup 0}) = -0.01 {+-} 0.13 (Stat.) {+-} 0.02 (Syst.), superseding previous measurements. The statistical significance of the signal is calculated to be 8.7{sigma}.

The authors present measurements of branching fractions in the b[yields] s[bar s]s penguin-dominated decays B[sup+][yields][phi]K[sup+] and B[sup 0][yields][phi]K[sup 0] in a sample of approximately 89 million B[bar B] pairs collected by the BABAR detector at the PEP-II asymmetric-energy B-meson Factory at SLAC.
