| dc.description | Using about 23M $B \bar B$ events collected in 1999-2000 with the BABAR detector, we report on the decays $B \to D^{(*)}\bar D^{(*)}K$ and $B^0 \to D^{*+}D^{*-}$. The branching fractions of the low background decay modes $B \to D^{(*)}\bar D^{(*)}K$ are determined to be ${\cal B}(B^0 \to D^{*-}D^{0}K^+) = (2.8 \pm 0.7 \pm 0.5)\times 10^{-3}$ and ${\cal B}(B^0 \to D^{*-}D^{*0}K^+) = (6.8 \pm 1.7 \pm 1.7)\times 10^{-3}$, where the first error quoted is statistical and the second systematic. Observation of a significant number of candidates in the color-suppressed decay mode $B^+\to D^{*+}D^{*-}K^+$ is reported with a branching fraction ${\cal B}(B^+\to D^{*+}D^{*-}K^+)= (3.4\pm 1.6\pm 0.9)\times 10^{-3}$. Decays of the type $B \to D^{(*)} \bar D^{(*)}$ can be used to provide a measurement of the parameter $\sin 2 β$ of the Unitarity Triangle. For this decay mode we measure a branching fraction of ${\cal BR} (B^0 \to D^{*+}D^{*-}) = (8.0 \pm 1.6\pm 1.2)\times 10^{-4}$. All results presented here are preliminary. | |
