Resonant contributions to three-body $B_{(s)}\to [D^{(\ast )},{\bar{D}}^{(\ast )}]K^{+}{K}^{-}$ decays in the perturbative QCD approach

Ya Li, Da-Cheng Yan, Zhou Rui +3

In this work, we study the $S$, $P$ and $D$ wave resonance contributions to three-body decays $B_{(s)}\to [D^{(\ast )},{\bar{D}}^{(\ast )}]K^{+}{K}^{-}$ by employing the perturbative QCD (PQC…
