B(Bs)→D(s)P, D(s)V, D(s)*P, and D(s)*V decays in the perturbative QCD approach

Two-body charmed decays B-(s) -> D(s)P, (D(s)P)-P-*, D(s)V, and (D(s)V)-V-*, where P and V denote the light pseudoscalar meson and vector meson, respectively, are analyzed in the perturbative QCD (pQCD) approach. Using the experimental data of six B -> DP channels, we test the D meson wave function by chi(2) fit. We give the branching ratios of all the charmed B decay channels, most of which agree with experiments amazingly well. The predicted B-s decays can be confronted with the future experimental data. By straightforward calculations, our pQCD approach gives the right relative strong phase of a(2)/a(1) that agrees with experiments. We also predict the percentage of transverse polarizations in B-(s) -> (DV)-V-* decay channels.
