Inspired by the five newly observed $\Omega^{0}_{c}$ states by the LHCbdetector, we study the $\Omega_{c}^{0}$ states as the $S-$wave molecularpentaquarks with $I=0$, $J^{P}=\frac{1}{2}^{-}$, $\frac{3}{2}^{-}$, and$\frac{5}{2}^{-}$ by solving the RGM equation in the framework of chiral quarkmodel. Both the energies and the decay widths are obtained in this work. Ourresults suggest that $\Omega_{c}(3119)^{0}$ can be explained as an $S-$waveresonance state of $\Xi D$ with $J^{P}=\frac{1}{2}^{-}$, and the decay channelsare the $S-$wave $\Xi_{c} K$ and $\Xi^{'}_{c}K$ . Other reported$\Omega^{0}_{c}$ states cannot be obtained in our present calculation. Another$\Omega_{c}^{0}$ state with much higher mass 3533 MeV with$J^{P}=\frac{5}{2}^{-}$ is also obtained. In addition, the calculation isextended to the $\Omega_{b}^{0}$ states, similar results as that of$\Omega^{0}_{c}$ are obtained.

Investigating the excited $\Omega^{0}_{c}$ states through $\Xi_{c}K$ and $\Xi^{'}_{c}K$ decay channels
