英文摘要	The newly observed Sigma(b) (6097) provides us a good chance to further construct the high excited states of the bottom baryon family. In this work, we explain the Sigma(b) (6097) to be a 1P state with JP = 5/2(-) or 3/2(-) by giving the mass spectrum analysis and the strong decay calculation, and predict the existence of 1P and 2S partners of the Sigma(b) (6097), where their masses and the corresponding decay behaviors are presented. Because of the success of describing the Sigma(b) (6097) and the former observed Xi(b) (6227) under the quasi-two-body treatment to the bottom baryons, we continue to predict the Omega(b) partners of Sigma(b) (6097) by the same method, which are the 1P and 2S states of the bss baryon system. Identifying these predicted bottom baryons will be a research topic full of challenge and opportunity for future experiments, especially the LHCb.
