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

The European Physical Journal C, May 2017

In this article, we assign $\Omega _c(3000)$, $\Omega _c(3050)$, $\Omega _c(3066)$, $\Omega _c(3090)$ and $\Omega _c(3119)$ to 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 $\Omega _c(3050)$, $\Omega _c(3066)$, $\Omega _c(3090)$ and $\Omega _c(3119)$ to 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 $\Omega _c(3000)$ 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.
