Observation of New ωc0 States Decaying to the Ξc+ K- Final State

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...

Descrição
Resumo: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.
