| Abstract: | Two new excited states, Ω (3185)0 and Ω (3327)0, are observed in the Ξ+ − 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 Ω0 states are confirmed, namely Ω (3000)0, Ω (3050)0, Ω (3065)0, Ω (3090)0, and Ω (3119)0. The masses and widths of these seven states are measured with the highest precision to date. |
