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

Abstract

Using the entire Belle data sample of 980 ${\mathrm{fb}}^{-1}$ 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 ${\Omega }_c(3090)$.
