Strong decays of the low-lying bottom strange baryons

In this work, the strong decay behaviors of the λ-mode low-lying Ξb and Ξ′b baryons are investigated within the 3P0 model. Our results suggest that all of the low-lying $$\bar{3}_{F}$$ states Ξb(2S), Ξb(1P), and Ξb(1D) have small decay widths of less than 20 MeV, and these states have good potentials to be observed in the Ξ′bπ and Ξ *′ π invariant masses. Further, most of the 6F multiplets are relatively narrow and may decay into the Ξbπ Ξ′bπ, Ξ *′ π, and $$\Lambda_{b}\bar{K}$$ final states. Considering the masses and strong decay behaviors, we can assign the newly observed Ξb(6100) resonance as the Ξb(1P) state with JP = 3/2− and interpret the Ξb(6227) structure as the JP = 3/2− Ξ′b(1P) state with a proper mixing angle. We expect that our predictions for these excited bottom strange baryons will provide helpful information for future experimental research.
