Abstract

Using the factorization approach and considering the contributions of the current-current, QCD penguin and electroweak penguin operators at the leading approximation, the decay amplitudes and decay widths of $B_{q} \to D_{q} (D_{q}^{*}) P$ and $B_{q} \to D_{q} (D_{q}^{*}) V$ transitions, where $q = u, d, s$ and P and V are pseudoscalar and vector mesons, are calculated in terms of the transition form factors of the $B_{q} \to D_{q}$ and $B_{q} \to D_{q}^{*}$ . Having computed those form factors in three-point QCD sum rules, the branching fraction for these decays are also evaluated. A comparison of our results with the predictions of the perturbative QCD as well as the existing experimental data is presented.
