Evidence for the decay psi(3770)->Xi(-)Xi(+) is observed with a significance of 4.5 sigma by analyzing the measured cross sections together with earlier BESIII results. For the other charmonium(-like) states psi(4040), psi(4160), Y(4230), Y(4360), psi(4415), and Y(4660), no significant signal of their decay to Xi(-)Xi(+) is found. For these states, upper limits of the products of the branching fraction and the electronic partial width at the 90% confidence level are provided.eninfo:eu-repo/semantics/openAccessE(+)-E(-) ExperimentsBranching FractionQcdElectroweak InteractionArticle11WOS:0011228413000012-s2.0-85178966219N/A10.1007/JHEP11(2023)228Q2
