# Strong decays of the ${\mathrm{Ξ}}_{b}(6227)$ as a ${\mathrm{Σ}}_{b}\overline{K}$ molecule

Yin Huang, Cheng-jian Xiao, Li-Sheng Geng, Jun He
We study the strong decays of the newly observed ${\mathrm{Ξ}}_{b}(6227)$ assuming that it is a pure ${\mathrm{Σ}}_{b}\overline{K}$ molecular state. Considering four possible spin-parity assingments ${J}^{P}=1/{2}^{±}$ and $3/{2}^{±}$, the partial decay widths of the ${\mathrm{Σ}}_{b}\overline{K}$ m...
