The Ξþ
c K− 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 Ξþ
c is reconstructed in the decay mode
pK−πþ. Five new, narrow excited Ω0
c states are observed: the Ωcð3000Þ0, Ωcð3050Þ0, Ωcð3066Þ0,
Ωcð3090Þ0, and Ωcð3119Þ0. Measurements of their masses and widths are reported.
