英文摘要	Selecting the newly observed Xi(b)(6227)(-) by LHCb as a study example, we decode its inner structure by giving the mass spectrum analysis and the investigation of its two-body strong decay behaviors. Our result indicates that the Xi(b)(6227)(-) is a good candidate of the P-wave Xi'(b) state with J(P) = 3/2(-) or 5/2(-). In addition, we further provide the information of the properties of the partners of the Xi(b)(6227)(-). These predicted states include three 2S states and the remaining 1P states in the bottom-strange baryon family. The calculated sizable Okubo-Zweig-Iizuka-allowed decay widths of these partners show that the experimental search for them becomes possible via LHCb. We have a reason to believe that the present study can be treated as a start point for constructing the highly excited bottom baryon spectroscopy.
