The newly observed Σb(6097) provides us a good chance to further construct the high excited states of the bottom baryon family. In this work, we explain the Σb(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 Σb(6097), where their masses and the corresponding decay behaviors are presented. Because of the success of describing the Σb(6097) and the former observed Ξb(6227) under the quasi-two-body treatment to the bottom baryons, we continue to predict the Ωb partners of Σb(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.
