The $\hat{I}›$-type P-wave bottom baryon states via the QCD sum rules

Abstract

Our study focuses on the $\hat{I}›$-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 $\hat{I}›$-type baryon) to investigate the $\hat{I}{›}_b$ and $\hat{I}{ž}_b$ states within the framework of the full QCD sum rules. The predicted masses show that the $\hat{I}{ž}_b(6087)$ and $\hat{I}{ž}_b(6095/6100)$ 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 $\hat{I}{›}_b(5912)$ and $\hat{I}{›}_b(5920)$ could be the P-wave bottom baryon states with the spin-parity $J^P={\frac{1}{2}}^{-}$ and ${\frac{3}{2}}^{-}$, respectively. The $\hat{I}{›}_b(5920)$ and $\hat{I}{ž}_b(6095/6100)$ maybe have two remarkable under-structures or Fock components at least.
