Abstract We study the semi-leptonic and non-leptonic B weak decays that are governed by the B→D(*) transitions. The branching ratios, CP asymmetries (CPAs) and polarization fractions of non−leptonic decays are investigated in the factorization approximation (FA). The B→D(*) form factors are estimated in the Salpeter method. Our estimation on branching ratios is in general agreement with existing experimental data. For CPAs and polarizations, comparisons among the FA results, the perturbative QCD predictions and experimental data are presented.
