Contributions of $K_0^{\ast }(1430)$ and $K_0^{\ast }(1950)$ in the charmed three-body $B$ meson decays

Bo-Yan Cui, Ya-Hui Chen

In this work, we investigate the resonant contributions of $K_0^{\ast }(1430)$ and $K_0^{\ast }(1950)$ in the three-body $B_{(s)}\to D_{(s)}K\pi$ within the perturbative QCD approach. The form f…
