Decay properties of P-wave bottom baryons within light-cone sum rules
Abstract We use the method of light-cone sum rules to study decay properties of P-wave bottom baryons belonging to the SU(3) flavor $$\mathbf {6}_F$$ 6F representation. In Cui et al. (Phys Rev D 99:094021, 2019) we have studied their mass spectrum and pionic decays, and found that the $$\varSigma _{...

| description | Abstract We use the method of light-cone sum rules to study decay properties of P-wave bottom baryons belonging to the SU(3) flavor $$\mathbf {6}_F$$ 6F representation. In Cui et al. (Phys Rev D 99:094021, 2019) we have studied their mass spectrum and pionic decays, and found that the $$\varSigma _{b}(6097)$$ Σb(6097) and $$\varXi _{b}(6227)$$ Ξb(6227) can be well interpreted as P-wave bottom baryons of $$J^P = 3/2^-$$ 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 $$\varXi _b({5/2}^-)$$ Ξb(5/2-) , that is the $$J^P = 5/2^-$$ JP=5/2- partner state of the $$\varXi _{b}(6227)$$ Ξb(6227) , in the $$\varXi _b({5/2}^-) \rightarrow \varXi _b^{*}\rho \rightarrow \varXi _b^{*}\pi \pi $$ Ξb(5/2-)→Ξb∗ρ→Ξb∗ππ decay process. Its mass is $$12 \pm 5$$ 12±5 MeV larger than that of the $$\varXi _{b}(6227)$$ Ξb(6227) . |
