We present measurements of branching fractions and CP-violating asymmetries in B-meson decays to {rho}{sup +}{pi}{sup 0}, {rho}{sup 0}{pi}{sup +} and {rho}{sup 0}{pi}{sup 0}. The data sample comprises 89 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. We find the charge-averaged branching fractions {Beta}(B{sup +} {yields} {rho}{sup +}{pi}{sup 0}) = (10.9 {+-} 1.9(stat) {+-} 1.9(syst)) x 10{sup -6} and {Beta}(B{sup 0} {yields} {rho}{sup 0}{pi}{sup +}) = (9.5 {+-} 1.1 {+-} 0.9) x 10{sup -6}, and we set a 90% confidence-level upper limit {Beta}(B{sup 0} {yields} {rho}{sup 0}{pi}{sup 0})

The most recent results obtained by the BABAR experiment at the PEP-II asymmetric-energy B Factory at SLAC on CP-violating asymmetries and branching fractions for neutral and charged B decays are presented here. The analysis was performed on a data sample of[approx] 88 million[Upsilon](4S)[yields] B[bar B] decays collected between 1999 and 2002. Using b[yields] c[bar c]s decays, we measure sin2[beta]= 0.741[+-] 0.067(stat)[+-] 0.034(syst). We also present sin2[beta] measurements from, b[yields] s[bar s]s and b[yields] c[bar c]d processes. From neutral B meson decays to two-body final states of charged pions and kaons, we derive for the CP violating parameters, S[sub[pi][pi]]= 0.02[+-] 0.34[+-] 0.05[-0.54,+0.58] and C[sub[pi][pi]]= -0.30[+-] 0.25[+-] 0.04[-0.72,+0.12]. First results for B[yields][pi][sup+][pi][sup -][pi][sup 0] and K[sup[+-]][pi][sup[-+]][pi][sup 0] final states dominated by the[rho][sup[+-]] resonance, are also presented.

We present updated measurements of branching fractions and CP-violating asymmetries for neutral B meson decays to two-body final states of charged pions and kaons. The results are obtained from a data sample of about 60 million [Upsilon](4S) 2!B{bar B} decays collected between 1999 and 2001 by the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. The sample contains 12415{sup +16} [pi][pi], 403 ± 24 K[pi], and 0.6{sub -7.4}{sup +8.0} KK candidates.
