Abstract

We study the three-body baryonic B decay Bˉs0pΛˉK\bar{B}^{0}_{s}\rightarrow p\bar{\Lambda} K^{-} within the framework of the pole model via the baryonic Λb\Lambda_{b} pole. In our calculation, we require the strong coupling constant gΛbBsΛg_{\Lambda_{b}B_{s}\Lambda} and investigate if gΛbBsΛ=10.49±1.57g_{\Lambda_{b}B_{s}\Lambda}=10.49\pm1.57 is adopted, the branching ratio agrees with the experimental result, reported by the LHCb collaboration.
