Study of $\overline{B^0}, B^- \to D^{(\ast)} p\bar{p}\ n\pi$, $n=0,1,2$ decays

Using a data sample of about $414 \textrm{fb}^{-1}$ collected with the {\it B{\footnotesize A}B{\footnotesize AR}} detector at the $\Upsilon(4S)$ resonance, consisting of $455 \times 10^6$ $B\bar{B}$ pairs, we measure the branching fractions for ten Cabibbo-favored $B$ decays to final states of the form $\overline{B^0}, B^- \to D^{(\ast)} p\bar{p}\ n\pi$, $n=0,1,2$ and study their decay dynamics.
