C., Aliberti, R., Amoroso, A., ... & Jeong, J. H. (2024). Measurement of e+ e−→ ωη′ cross sections at $$\sqrt {s} $$= 2.000 to 3.080 GeV. Journal of high energy physics, 2024(7), 1-18.10298479http://dx.doi.org/10.1007/JHEP07(2024)093https://hdl.handle.net/20.500.12713/7165We measured the Born cross sections for the process e+e− → ωη′ at 22 center-of-mass energies from 2.000 to 3.080 GeV with the BESIII detector at the BEPCII collider. We observed a resonant structure with a statistical significance of 9.6σ. A Breit-Wigner fit determines its mass to be MR = (2153 ± 30 ± 31) MeV/c2 and its width to be ΓR = (167 ± 77 ± 7) MeV, where the first uncertainties are statistical and the second are systematic. © The Author(s) 2024.eninfo:eu-repo/semantics/openAccessSpectroscopyParticle and Resonance Productione+-e− ExperimentsArticle20247WOS:0013501059000012-s2.0-85198746268Q110.1007/JHEP07(2024)093Q1
