Analysis of the ${\Omega }_b(6316)$, ${\Omega }_b(6330)$, ${\Omega }_b(6340)$ and ${\Omega }_b(6350)$ with QCD sum rules

Abstract

In this article, we introduce an explicit P-wave to construct three-quark currents to study the P-wave ${\Omega }_b$ states with the full QCD sum rules. The predicted masses have a hierarchy if the same parameters are chosen and favor assigning the ${\Omega }_b(6316)$, ${\Omega }_b(6330)$, ${\Omega }_b(6340)$ and ${\Omega }_b(6350)$ to be the P-wave ${\Omega }_b$ states with the $J^P={\frac{3}{2}}^{-}$, ${\frac{1}{2}}^{-}$, ${\frac{5}{2}}^{-}$ and ${\frac{3}{2}}^{-}$, respectively.
