Two new excited states, ωc(3185)0 and ωc(3327)0, are observed in the Ξc+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 ωc0 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.

Abstract
Two new excited states, ωc(3185)0 and ωc(3327)0, are observed in the Ξc+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 ωc0 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.File in questo prodotto:
