Analysis of the ${\Omega }_c(3000)$, ${\Omega }_c(3050)$, ${\Omega }_c(3066)$, ${\Omega }_c(3090)$ and ${\Omega }_c(3119)$ with QCD sum rules

Abstract

In this article, we assign the ${\Omega }_c(3000)$, ${\Omega }_c(3050)$, ${\Omega }_c(3066)$, ${\Omega }_c(3090)$ and ${\Omega }_c(3119)$ to be the P-wave baryon states with $J^P={\frac{1}{2}}^{-}$, ${\frac{1}{2}}^{-}$, ${\frac{3}{2}}^{-}$, ${\frac{3}{2}}^{-}$ and ${\frac{5}{2}}^{-}$, respectively, and study them with the QCD sum rules by introducing an explicit relative P-wave between the two $s$ quarks. The predictions support assigning the ${\Omega }_c(3050)$, ${\Omega }_c(3066)$, ${\Omega }_c(3090)$ and ${\Omega }_c(3119)$ to be the P-wave baryon states with $J^P={\frac{1}{2}}^{-}$, ${\frac{3}{2}}^{-}$, ${\frac{3}{2}}^{-}$ and ${\frac{5}{2}}^{-}$, respectively, where the two $s$ quarks are in relative P-wave; while the ${\Omega }_c(3000)$ can be assigned to the P-wave baryon state with $J^P={\frac{1}{2}}^{-}$, where the two $s$ quarks are in relative S-wave.
