Born cross section measurements of two-body intermediate resonance states with statistical significance greater than 5 sigma are presented, such as f(0)(500), f(0)(980), f(2)(1270), f(0)(1370), b(1)(1235)(+/-), and rho(1450)(+/-). In addition, evidence of a resonance state in e(+)e(-) -> pi(+)pi(-)omega production is found. The mass of this state obtained by line shape fitting is about 4.2 GeV/c(2), which is consistent with the production of psi(4160) or Y(4220).eninfo:eu-repo/semantics/openAccessE(+)-E(-) ExperimentsQcdQuarkoniumArticle8WOS:0010624213000012-s2.0-85169134251N/A10.1007/JHEP08(2023)159Q2
