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.11 p.application/pdfeng(c) American Physical Society, 2023Cromodinàmica quànticaQuarksHadronsQuantum chromodynamicsQuarksHadronsinfo:eu-repo/semantics/article7547852025-06-23info:eu-repo/semantics/openAccess
