Abstract

The newly observed Σb(6097)\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 Σb(6097)\Sigma_b(6097) to be a 1P1P state with JP=5/2J^P=5/2^- or 3/23/2^- by giving the mass spectrum analysis and the strong decay calculation, and predict the existence of 1P1P and 2S2S partners of the Σb(6097)\Sigma_b(6097), where their masses and the corresponding decay behaviors are presented. Because of the success of describing the Σb(6097)\Sigma_b(6097) and the former observed Ξb(6227)\Xi_b(6227) under the quasi-two-body treatment to the bottom baryons, we continue to predict the Ωb\Omega_b partners of Σb(6097)\Sigma_b(6097) by the same method, which are the 1P1P and 2S2S states of the bssbss baryon system. Identifying these predicted bottom baryons will be a research topic full of challenge and opportunity for future experiments especially the LHCb.
