Branching ratios of $B^{+}\to D^{(\ast )+}{K}^{(\ast )0}$ decays in perturbative QCD approach

Ge-Liang Song, Cai-Dian Lü

We study the rare decays $B^{+}\to D^{(\ast )+}{K}^{(\ast )0}$, which can occur only via annihilation type diagrams in the standard model. We calculate all of the four modes, $B \to PP, VP, P…
