Abstract

The e^+e^- annihilation data recorded with the BABAR detector has been used to study B decays to D_s^(*) and D^* mesons. The production fraction of inclusive D_s^(*) and the corresponding momentum spectra have been determined. Exclusive decays B^0 --> D^{*-}D_s^{(*)+} have been identified with a partial reconstruction technique and their branching fractions have been measured. We also report branching fraction measurements for the exclusive hadronic modes B^0 --> D^{*-} pi^+ and B^0 --> D^{*-} rho^+.
