Abstract

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