An obvious structure is observed in the Born cross section line shape. Fit as a Breit-Wigner resonance, it has a statistical significance of 6.3 sigma and a mass and width of M = (2111 +/- 43 +/- 25) MeV/c(2) and Gamma = (135 +/- 34 +/- 30) MeV, where the uncertainties are statistical and systematic, respectively. These measured resonance parameters agree with the measurements of BABAR in e(+)e(-) -> eta'pi(+)pi(-) and BESIII in e+e(-) -> omega pi(0) within two standard deviations.eninfo:eu-repo/semantics/openAccessMesonsResonancesI=0PiMeasurement of the Born cross sections for e+e- ? ?'?+ ?- a t center-of-mass energies between 2.00 and 3.08 GeVArticle2-s2.0-8510551779910.1103/PhysRevD.103.0720077Q1103Q1WOS:000648580900001
