Abstract

The Ξ_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 Ξ_c⁺ is reconstructed in the decay mode pK^-π⁺. Five new, narrow excited Ω_c⁰ states are observed: the Ω_c(3000)⁰, Ω_c(3050)⁰, Ω_c(3066)⁰, Ω_c(3090)⁰, and Ω_c(3119)⁰. Measurements of their masses and widths are reported.
