Observation of Excited ${\mathrm{\Omega }}_c$ Charmed Baryons in $e^{+}{e}^{-}$ Collisions

Using the entire Belle data sample of 980 ${\mathrm{f}\mathrm{b}}^{-1}$ of $e^{+}{e}^{-}$ collisions, we present the results of a study of excited ${\mathrm{\Omega }}_c$ charmed baryons in the decay mode ${\mathrm{\Xi }}_c^{+}{K}^{-}$. We show confirmation of four of the five narrow states reported by the LHCb Collaboration: the ${\mathrm{\Omega }}_c(3000)$ , ${\mathrm{\Omega }}_c(3050)$, ${\mathrm{\Omega }}_c(3066)$, and ${\mathrm{\Omega }}_c(3090)$.
