Two new excited states, Omegac(3185)0 and Omegac(3327)0, are observed in the Xic+K- 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 Omega0c states are confirmed, namely Omegac(3000)0, Omegac(3050)0, Omegac(3065)0, Omegac(3090)0, and Omegac(3119)0. The masses and widths of these seven states are measured with the highest precision to date.

Abstract

Two new excited states, Omegac(3185)0 and Omegac(3327)0, are observed in the Xic+K- 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 Omega0c states are confirmed, namely Omegac(3000)0, Omegac(3050)0, Omegac(3065)0, Omegac(3090)0, and Omegac(3119)0. The masses and widths of these seven states are measured with the highest precision to date.
