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 Ω⁰_c 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.
