The authors present a model-independent measurement of[Beta](D[sub s][sup -][yields][phi][pi][sup -])/[Beta](D[sup 0][yields] K[sup -][pi][sup+]) by partially reconstructing the decay[bar B][sup 0][yields] D*[sup+]D*[sub s][sup -]. Using data collected with the CLEO II detector at CESR, they determine[Beta](D[sub s][sup -][yields][phi][pi][sup -])/[Beta](D[sup 0][yields] K[sup -][pi][sup+])= 0.92[+-] 0.20(stat.)[+-] 0.11(syst.). Their measurement of[Beta](D[sup 0][yields] K[sup -][pi][sup+]) then gives[Beta](D[sub s][sup -][yields][phi][pi][sup -])= (3.59[+-] 0.77[+-] 0.48)%.

The authors present model-independent measurements of the branching fractions[Beta](B[sup 0][yields] D*[sub s][sup+] D*[sup -]) and[Beta](D[sub s][sup+][yields][phi][pi][sup+]) based on 19.3 fb[sup -1] of data collected by the BABAR detector at the PEP-II e[sup+]e[sup -] B Factory. Neutral B-meson decays to the D*[sub s][sup+]D*[sup -] final state are selected with a partial reconstruction of the D*[sub s][sup+]; that is, only the D*[sup -] and the soft photon from the decay D*[sub s][sup+][yields] D[sub s][sup+][gamma] are reconstructed. The branching fraction[Beta](B[sup 0][yields] D*[sub s][sup+] D*[sup -]) is extracted from these event yields, while[Beta](D[sub s][sup+][yields][phi][pi][sup+]) is determined by combining this result with a previous measurement of the product[Beta](B[sup 0][yields] D*[sub s][sup+] D*[sup -]) x[Beta](D[sub s][sup+][yields][phi][pi][sup+]) with partial reconstruction of the D*[sup -]. They obtain the following preliminary results:[Beta](B[sup 0][yields] D*[sub s][sup+] D*[sup -])= (1.50[+-] 0.16[+-] 0.12)%, [Beta](D[sub s][sup+][yields][phi][pi][sup+])= (4.7[+-] 0.6[+-] 0.8)% where the first error is statistical, and the second systematic.

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 have measured a preliminary value for the branching ratio (Gamma)(D*[sup +][sub s] --> D[sup +][sub s][pi][sup 0])/[Gamma](D*[sup +][sub s] --> D[sup +][sub s][gamma]) = 0.0621 [+-] 0.0049(stat) [+-] 0.0063(syst), which is consistent with the previous measurement, but has higher precision. They have also measured [Gamma](D*[sup 0] --> D[sup 0][pi][sup 0])/[Gamma](D*[sup 0] --> D[sup 0][gamma]) = 1.740 [+-] 0.020(stat) [+-] 0.125(syst), which is more precise than, and in agreement with, the world average. The branching fraction B(D*[sup +][sub s] --> D[sup +][sub s][pi][sup 0]) = 0.0585 [+-] 0.0043(stat) [+-] 0.0056(syst) is larger than the theoretical prediction, which is in the 1-3% range. However, it should be noted that the theory predicts a strong correlation between B(D*[sup +][sub s] --> D[sup +][sub s][pi][sup 0]) and B(D*[sup +] --> D[sup +][gamma]); for B(D*[sup +] --> D[sup +][gamma]) [approx]1%, B(D*[sup +][sub s] -- D[sup +][sub s][pi][sup 0]) is expected to be greatly enhanced.

We present a measurement of the absolute branching fraction for D[sup 0][yields] K[sup -][pi][sup+] using the reconstruction of the decay chain[bar B][yields] D*[sup+]X[ell][sup -][bar[nu]], D*[sup+][yields] D[sup 0][pi][sup+] where only the lepton and the low-momentum pion from the D*[sup+] are detected. With data collected by the CLEO II detector at the Cornell Electron Storage Ring, we have determined Br(D[sup 0][yields] K[sup -][pi][sup+])=[3.81[+-] 0.15(stat.)[+-] 0.16(syst.)]%.

The authors present measurements of the branching fractions?(B° → D*−D*{sub s}) and?(D{sub s}+ →??+), based on 123 x 106?(4S) → B{bar B} decays collected by the BABAR detector at the PEP-II asymmetric-energy e+e− B factory. A partial reconstruction technique is used to measure?(B° → D*−D*{sub s}+) and the decay chain is fully reconstructed to measure the branching fraction product?(B° → D*− D*{sub s}+) x?(D{sub s}+ →??+). Comparing these two measurements provides a model-independent determination of the D{sub s}+ →??+ branching fraction. They obtain?(B° → D*−D*{sub s}+) = (1.88 ± 0.09 ± 0.17)% and?(D{sub s}+ →??+) = (4.81 ± 0.52 ± 0.38)%, where the first uncertainties are statistical and the second systematic.
