Description
In 2021, the LHCb Collaboration observed three new $\Xi_{b}$ baryonic states: $\Xi_{b}(6227)$, $\Xi_{b}(6327)$, and $\Xi_{b}(6333)$. The spin-parity of these states remains undetermined. This study examines the mass spectra of the $\Xi_{b}^{'}$ baryon. To achieve this aim, we utilize the framework of the relativistic flux tube model, incorporating a heavy bottom quark and a light diquark representation of baryons. We incorporate the spin-dependent interactions in the limit of heavy quark symmetry. The results obtained align well with the existing experimental masses. The findings indicate that the $\Xi_{b}(6227)$ is a viable candidate for the P-wave $\Xi_{b}^{'}$ baryon with $J^P$ value $\frac{1}{2}^{-}$ or $\frac{3}{2}^{-}$. Additionally, the baryons $\Xi_{b}(6327)$ and $\Xi_{b}(6333)$ can be effectively understood as P-wave $\Xi_{b}^{'}$ baryons with $J^P$ values $\frac{3}{2}^{-}$ and $\frac{5}{2}^{-}$, respectively. This study can contribute to constructing the highly excited states of the $\Xi_{b}^{'}$ baryonic family.
