The significance of the ω(2012)- signal is 4.2σ after considering the systematic uncertainties. The ratio of the branching fraction of ωc0→π+ω(2012)-→π+(K̄Ξ)- relative to that of ωc0→π+ω- is calculated to be 0.220±0.059(stat.)±0.035(syst.). The individual ratios of the branching fractions of the two isospin modes are also determined and found to be B(ωc0→π+ω(2012)-)×B(ω(2012)-→K-Ξ0)/B(ωc0→π+K-Ξ0)=(9.6±3.2(stat.) ±1.8(syst.))% and B(ωc0→π+ω(2012)-)×B(ω(2012)-→K̄0Ξ-)/B(ωc0→π+K̄0Ξ-)=(5.5±2.8(stat.) ±0.7(syst.))%.9 page(s)application/pdfenIn CopyrightArticle - Refereedhttps://doi.org/10.1103/PhysRevD.104.0520051045Piilonen, Leo [0000-0001-6836-0748]2470-0029
