Abstract : The Ξ+cK− mass spectrum is studied with a sample of pp collision data corresponding to an integrated luminosity of 3.3 fb−1, collected by the LHCb experiment. The Ξ+c is reconstructed in the decay mode pK−π+. Five new, narrow excited Ω0c 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.
