Certain hadronic two-body decays of $B$ mesons are dominated by penguin diagrams. The ratios of rates for several such decays, including $\Gamma(B^0 \to \overline{K}^{*0} K^0)/\Gamma(B^0 \to \phi K^0)$, $\Gamma(B^0 \to \overline{K}^{*0}…

The two-body mesonic $B$ decays induced only via a single $W$-exchange or annihilation quark diagram, such as $B^-_u\rightarrow D^{(*)-}_sK^{(*)0}$ and $\bar{B}^0_d\rightarrow D^{(*)+}_sK^{(*)-}$, are analyzed in the factorization…

An updated analysis of the two-body $D\to PP, V\!P$ and $VV$ decays within the framework of the topological diagram approach is performed. A global fit to the Cabibbo-favored (CF) modes in the $V\!P$ sector gives many solutions with…

We consider the semileptonic and nonleptonic $D_s$ decay modes to final states with $\eta$ and $\eta^\prime$. We use QCD sum rules to determine the $D_s \to \eta$ form factor $f_+^\eta$, and a generalized factorization ansatz to compute…

We analyze $D \to P V$, $D \to PP$ and $D \to VV$ decays within a model developed to describe the semileptonic decays $D \to V l \nu_l$ and $D\to P l \nu_l$. This model combines the heavy quark effective Lagrangian and chiral perturbation…
