In this paper the studies of three different B decays to hadronic states are presented. These results are based on 1999-2003 dataset collected by the BaBar experiment at the PEP-II e+e- storage ring at the Stanford Linear Accelerator Center. The measurements are the hadronic branching fraction of B+ -> J/psi p Lambda-bar, B0 -> J/psi p p-bar, B0 -> D*+D-, and the direct CP-asymmetry in B0 -> D0(CP) K- channels.
The e+e- annihilation data recorded with the BABAR detector has been used to study B^0 decays to Ds^(*)+ and D^*-$ mesons. The production fraction of inclusive Ds^(*)+ and the corresponding momentum spectra have been determined. Exclusive decays B^0 --> D^*- Ds^(*)+ have been identified with a partial reconstruction technique and their branching ratios have been measured. Fully reconstructed B^0 decays in the hadronic modes B^0 --> D^*- pi+ andB^0 --> D^*- rho+ have been also studied and the measurement of their absolute branching fractions is reported.
