Quasi-two-body decays $B\to D{K}^{\ast }(892)\to DK\pi$ in the perturbative QCD approach

Ai-Jun Ma, Wen-Fei Wang, Ya Li +1

We study the quasi-two-body decays $B\to D{K}^{\ast }(892)\to DK\pi$ by employing the perturbative QCD approach. The two-meson distribution amplitudes $Φ_{Kπ}^{\text{$P$-wave}}$ are adopt…
