The virtual contributions from $K^{\ast }$ in the $B\to K^{\ast }\pi h$ and $B\to K\rho h$ decays

Ai-Jun Ma, Wen-Fei Wang

Inspired by the significant virtual contributions of the subprocesses $D^{\ast }/B^{\ast }\to D\pi$ and $\rho \to \omega \pi /K\bar{K}$ in the three-body hadronic $B$ meson decays, we study the off-shell…
