P-wave $\Omega_{b}$ states: masses and pole residues.

In this paper, we consider all P-wave $\Omega_{b}$ states represented by interpolating currents with a derivative and calculate the corresponding masses and pole residues with the method of QCD sum rule. The masses can be compared with the experimental observations. According to our calculation, it is reasonable to assign the observed $\Omega_{b}(6316)$, $\Omega_{b}(6330)$, $\Omega_{b}(6340)$ and $\Omega_{b}(6350)$ to be P-wave excited $\Omega_{b}$ states with $J^{P}$ quantum number $\frac{3}{2}^{-}$, $\frac{1}{2}^{-}$, $\frac{3}{2}^{-}$ and $\frac{3}{2}^{-}$, respectively. The pole residues are necessary input parameters when studying other properties of the corresponding states by QCD sum rule method or light-cone sum rule method.
