Abstract

We present preliminary results on hadronic decays of B mesons, based on data recorded at the Upsilon(4S) resonance with the BABAR detector at the PEP-II B-factory at SLAC. We measure branching fractions of many B decay modes, including decays to J/psi phi K, J/psi pi^+ pi^- and eta_c K final states. We report the observation of the decay B --> D_s pi^- and the first measurement of the flavor-tagged D meson production in B^0 decays. Since their preliminary nature, the results presented in this paper are based on different data samples.
