Observation of Excited $Omega_c$ Charmed Baryons in $e^+e^-$ Collisions

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