Abstract / Description of output

Two new excited states, Ωc(3185)0 and Ωc(3327)0, are observed in the Ξ+cK− invariant-mass spectrum using proton-proton collision data collected by the LHCb experiment, corresponding to an integrated luminosity of 9  fb−1. Five previously observed excited Ω0c states are confirmed, namely Ωc(3000)0, Ωc(3050)0, Ωc(3065)0, Ωc(3090)0, and Ωc(3119)0. The masses and widths of these seven states are measured with the highest precision to date.
