The Ξc+K- mass spectrum is studied with a sample of p p collision data corresponding to an integrated luminosity of 3.3 fb-1, collected by the LHCb experiment. The Ξc+ is reconstructed in the decay mode p K-π+. Five new, narrow excited Ωc0 states are observed: the Ωc(3000 )0, Ωc(3050 )0, Ωc(3066 )0, Ωc(3090 )0, and Ωc(3119 )0. Measurements of their masses and widths are reported.
