We report updated branching fraction measurements of the color-suppressed decays {bar B}° → D°?°, D*°?°, D°?, D*°?, D°?, D*°?, D°?', and D*°?'. We measure the branching fractions (x10−4):?({bar B}° → D°?°) = 2.69 ± 0.09 ± 0.13,?({bar B}° → D*°?°) = 3.05 ± 0.14 ± 0.28,?({bar B}° → D°?) = 2.53 ± 0.09 ± 0.11,?({bar B}° → D*°?) = 2.69 ± 0.14 ± 0.23,?({bar B}° → D°?) = 2.57 ± 0.11 ± 0.14,?({bar B}° → D*°?) = 4.55 ± 0.24 ± 0.39,?({bar B}° → D°?') = 1.48 ± 0.13 ± 0.07, and?({bar B}° → D*°?') = 1.49 ± 0.22 ± 0.15. We also present the first measurement of the longitudinal polarization fraction of the decay channel D*°?, f{sub L} = (66.5 ± 4.7 ± 1.5)%. In the above, the first uncertainty is statistical and the second is systematic. The results are based on a sample of (454 ± 5) x 106 B{bar B} pairs collected at the?(4S) resonance, with the BABAR detector at the PEP-II storage rings at SLAC. The measurements are the most precise determinations of these quantities from a single experiment. They are compared to theoretical predictions obtained by factorization, Soft Collinear Effective Theory (SCET) and perturbative QCD (pQCD). We find that the presence of final state interactions is favored and the measurements are in better agreement with SCET than with pQCD.

The authors present a study of the decays {bar B}{sup 0} {yields} D{sup (*)0}{bar K}{sup (*)0} using a sample of 226 million {Upsilon}(4S) {yields} B{bar B} decays collected with the BABAR detector at the PEP-II asymmetric-energy e{sup +}e{sup -} collider at SLAC. They report evidence for the decay of B{sup 0} and {bar B}{sup 0} mesons to the D*{sup 0}K{sub S}{sup 0} final state with an average branching fraction {Beta}({bar B}{sup 0} {yields} D*{sup 0} {bar K}{sup 0}) {triple_bond} {Beta}({bar B}{sup 0} {yields} D*{sup 0} {bar K}{sup 0}) + {Beta}(B{sup 0} {yields} D*{sup 0}K{sup 0})/2 = (3.6 {+-} 1.2 {+-} 0.3) x 10{sup -5}.

Using 65 million {Upsilon}(4S) {yields} B{bar B} events collected with the BABAR detector at the PEP-II e{sup +}e{sup -} storage ring at the Stanford Linear Accelerator Center, they measure the color-favored branching fractions {Beta}({bar B}{sup 0} {yields} D{sup +}{pi}{sup -}) = (2.63 {+-} 0.05 {+-} 0.22) x 10{sup -3}, {Beta}({bar B}{sup 0} {yields} D*{sup +}{pi}{sup -}) = (2.79 {+-} 0.08 {+-} 0.18) x 10{sup -3}, {Beta}(B{sup -} {yields} D{sup 0}{pi}{sup -}) = (4.90 {+-} 0.07 {+-} 0.23) x 10{sup -3} and {Beta}(B{sup -} {yields} D*{sup 0} {pi}{sup -}) = (5.52 {+-} 0.17 {+-} 0.43) x 10{sup -3}, where the first error is statistical and the second is systematic. With these results and the current world average for the branching fraction for the color-suppressed decay {bar B}{sup 0} {yields} D{sup (*)0}{pi}{sup 0}, the cosines of the strong phase difference {delta} between the I = 1/2 and I = 3/2 isospin amplitudes are determined to be cos{sigma} = 0.860{sub -0.006-0.028}{sup +0.007+0.029} for the {bar B} {yields} D{pi} process and cos{sigma} = 0.917{sub -0.016-0.051}{sup +0.018+0.059} for the {bar B} {yields} D*{pi} process. The results for cos{delta} suggest that final-state interactions are presented in the D{pi} system.

The authors present a study of the decays B[sup 0][yields] D[sub s][sup (*)+] D*[sup -], using 20.8 fb[sup -1] of e[sup+]e[sup -] annihilation data recorded with the BABAR detector. The analysis is conducted with a partial reconstruction technique, in which only the D[sub s][sup (*)+] and the soft pion from the D*[sup -] decay are reconstructed. They measure the branching fractions[Beta](B[sup 0][yields] D[sub s][sup (*)+] D*[sup -])= (1.03[+-] 0.14[+-] 0.13[+-] 0.26)% and[Beta](B[sup 0][yields] D[sub s][sup (*)+] D*[sup -])= (1.97[+-] 0.15[+-] 0.30[+-] 0.49)%, where the first error is statistical, the second is systematic, and the third is the error due to the D[sub s][sup+][yields][phi][pi][sup+] branching fraction uncertainty. From the B[sup 0][yields] D[sub s][sup (*)+] D*[sup -] angular distributions, they measure the fraction of longitudinal polarization[Lambda][sub L]/[Lambda]= (51.9[+-] 5.0[+-] 2.8)%, which is consistent with theoretical predictions based on factorization.

We report a preliminary branching fraction of (1.80 {+-} 0.37{sub stat.} {+-} 0.23{sub syst.}) x 10{sup -4} for the charmless exclusive semileptonic B{sup +} {yields} {pi}{sup 0}{ell}{sup +}{nu} decay, where {ell} can be either a muon or an electron. This result is based on data corresponding to an integrated luminosity of 81 fb{sup -1} collected at the {Upsilon}(4S) resonance with the BABAR detector. The analysis uses B{bar B} events that are tagged by a B meson reconstructed in the semileptonic B{sup -} {yields} D{sup 0}{ell}{sup -}{bar {nu}}(X) decays, where X can be either a {gamma} or a {pi}{sup 0} from a D* decay.

We present measurements of the decays B[sup 0][yields] D[sub s][sup (*)+] D*[sup -], using data recorded by the BABAR detector in 1999 and 2000, consisting of 20.8 fb[sup -1]. The analysis is conducted with a partial reconstruction technique, in which only the D[sub s][sup (*)+] and the soft pion from the D*[sup -] decay are reconstructed. From the observed rates, we measure the branching fractions[Beta](B[sup 0][yields] D[sub s][sup+] D*[sup -])= (1.03[+-] 0.14[+-] 0.13[+-] 0.26)% and[Beta](B[sup 0][yields] D*[sub s][sup+] D*[sup -])= (1.97[+-] 0.15[+-] 0.30[+-] 0.49)%, where the first error is statistical, the second is systematic, and the third is the error due to the D[sub s][sup+][yields][phi][pi][sup+] branching fraction uncertainty. From the[Beta](B[sup 0][yields] D*[sub s][sup+] D*[sup -]) angular distributions, we measure the fraction of longitudinal polarization[Lambda][sub L]/[Lambda]= (51.9[+-] 5.0[+-] 2.8)%, which is consistent with the theoretical prediction, based on factorization. These results are preliminary.
