- W4319452334 abstract "The detection of radially excited heavy meson states in recent years and measurement of heavy meson decays, particularly $B_c^+to J/psi D_s^+$ and $B_c^+to J/psi D_s^{*+}$, by the LHCb and ATLAS Collaborations, have aroused a lot of theoretical interest in the nonleptonic decays of $b$-flavored mesons. In this paper, we study the exclusive two-body nonleptonic $bar{B}^0$, $bar{B_s^0}$, $B^-$ and $B_c^-$-meson decays to two vector meson ($V_1(nS)V_2$) states. Assuming the factorization hypothesis, we calculate the weak-decay form factors from the overlapping integrals of meson wave functions, in the framework of relativistic independent quark (RIQ) model. We find a few dominant decay modes: $B^-to D^{*0}rho^-$, $bar{B^0}to D^{*+}rho^-$, $bar{B_s^0}to D_s^{*+}rho^-$, $B^-to J/psi K^{*-}$ and $B_c^-to J/psi D_s^{*-}$ with predicted branching fractions of 1.54, 1.42, 1.17, 0.53 and 0.52 (in $%$), which are experimentally accessible. The predicted branching fractions for corresponding decay modes to excited ($2S$) states, obtained in the order ${cal O }(10^{-3}-10^{-4})$ lie within the detection accuracy of the current experiments at LHCb and Tevatron. The sizeable $CP$-odd fractions predicted for $B_c^-$-meson decays to two charmful states: $D^{*0}D^{*-}_{(s)}$ and $bar{D}^{*0}D^{*-}_{(s)}$ indicate significant $CP$-violation that hints at the so-called new physics beyond the standard model." @default.
