We use the method of light-cone sum rules to study decay properties of P-wave bottom baryons belonging to the SU(3) flavor 6Frepresentation. In Cui et al. (Phys Rev D 99:094021, 2019) we have studied their mass spectrum and pionic decays, and found that the sigma b(6097) and Xi b(6227) can be well interpreted as P-wave bottom baryons of JP=3/2-. In this paper we further study their decays into ground-state bottom baryons and vector mesons. We propose to search for a new state Xi b(5/2-), that is the JP=5/2- partner state of the Xi b(6227), in the Xi b(5/2-)->Xi b*rho ->Xi b*pi pi decay process. Its mass is 12 +/- 5MeV larger than that of the Xi b(6227).
