The $\mathrm{\Lambda }$-type P-wave bottom baryon states via the QCD sum rules

Our study focuses on the $\mathrm{\Lambda }$-type P-wave bottom baryon states with the spin-parity $J^P={\frac{1}{2}}^{-}$, ${\frac{3}{2}}^{-}$. We introduce an explicit P-wave between the two light quarks in the interpolating currents (and the two light quarks are antisymmetric in flavor space, therefore leads to the name $\mathrm{\Lambda }$-type baryon) to investigate the ${\mathrm{\Lambda }}_b$ and ${\mathrm{\Xi }}_b$ states within the framework of the full QCD sum rules. The predicted masses show that the ${\mathrm{\Xi }}_b(6087)$ and ${\mathrm{\Xi }}_b(6095\mathrm{/}6100)$ could to be the P-wave bottom-strange baryon states with the spin-parity $J^P={\frac{1}{2}}^{-}$ and ${\frac{3}{2}}^{-}$, respectively, meanwhile, the ${\mathrm{\Lambda }}_b(5912)$ and ${\mathrm{\Lambda }}_b(5920)$ could be the P-wave bottom baryon states with the spin-parity $J^P={\frac{1}{2}}^{-}$ and ${\frac{3}{2}}^{-}$, respectively. The ${\mathrm{\Lambda }}_b(5920)$ and ${\mathrm{\Xi }}_b(6095\mathrm{/}6100)$ maybe have two remarkable under-structures or Fock components at least.
