The angular distributions and the differential branching fraction of the decay B0→K*(892)0?+?- are studied using data corresponding to an integrated luminosity of 20.5 fb-1 collected with the CMS detector at the LHC in pp collisions at √s = 8 TeV. Additionally, from 1430 signal decays, the forward–backward asymmetry of the muons, the K*(892)0 longitudinal polarization fraction, and the differential branching fraction are determined as a function of the dimuon invariant mass squared. Our measurements are among the most precise to date and are in good agreement with standard model predictions.

We present measurements of the decays B° → D{sub s}{sup (*)+} D*−, using data recorded by the BABAR detector in 1999 and 2000, consisting of 20.8 fb−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*− decay are reconstructed. From the observed rates, we measure the branching fractions?(B° → D{sub s} D*−) = (1.03 ± 0.14 ± 0.13 ± 0.26)% and?(B° → D*{sub s}+ D*−) = (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}+ →??+ branching fraction uncertainty. From the?(B° → D*{sub s}+ D*−) angular distributions, we measure the fraction of longitudinal polarization?{sub L}/? = (51.9 ± 5.0 ± 2.8)%, which is consistent with the theoretical prediction, based on factorization. These results are preliminary.

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.

The authors present model-independent measurements of the branching fractions?(B° → D*{sub s} D*−) and?(D{sub s}+ →??+) based on 19.3 fb−1 of data collected by the BABAR detector at the PEP-II e+e− B Factory. Neutral B-meson decays to the D*{sub s}+D*− final state are selected with a partial reconstruction of the D*{sub s}+; that is, only the D*− and the soft photon from the decay D*{sub s}+ → D{sub s}+? are reconstructed. The branching fraction?(B° → D*{sub s}+ D*−) is extracted from these event yields, while?(D{sub s}+ →??+) is determined by combining this result with a previous measurement of the product?(B° → D*{sub s}+ D*−) x?(D{sub s}+ →??+) with partial reconstruction of the D*−. They obtain the following preliminary results:?(B° → D*{sub s}+ D*−) = (1.50 ± 0.16 ± 0.12)%,?(D{sub s}+ →??+) = (4.7 ± 0.6 ± 0.8)% where the first error is statistical, and the second systematic.

Using data taken with the CLEO II detector, we present the first full angular analysis in the color-suppressed modes B[sup 0][yields] J/[psi] K*[sup 0] and B[sup+][yields] J/[psi] K*[sup+]. This leads to a complete determination of the decay amplitudes of these modes. In addition, we update the branching fractions for B[yields] J/[psi] K and B[yields] J/[psi] K*.
