We use the method of light-cone sum rules to study decay properties of P-wave bottom baryons belonging to the SU(3) flavor representation. In Cui et al. (Phys Rev D 99:094021, 2019) we have studied their mass spectrum and pionic decays, and found that the and can be well interpreted as P-wave bottom baryons of . In this paper we further study their decays into ground-state bottom baryons and vector mesons. We propose to search for a new state , that is the partner state of the , in the decay process. Its mass is MeV larger than that of the .
