Cross section measurements of the processes e+e− → ωπ0 and ωη at center-of-mass energies between 3.773 and 4.701 GeV

Abstract: The Born cross sections of the processes e+e− → ωπ0 and e+e− → ωη are measured at center-of-mass energies between 3.773 and 4.701 GeV using a total integrated luminosity of 22.7 fb−1 collected with the BESIII detector operating at the BEPCII collider. A simple s−n dependence for the continuum process can describe the measured Born cross sections. No significant contributions from the ψ(4160), Y(4230), Y(4360), ψ(4415), Y(4660) resonances are found, which indicates relative small branching fractions for these r… Show more

“…Recently, BESIII measured the cross section of e + e − → ppη and e + e − → ppω, and no clear structure is observed on the cross section line shape [7]. It is same for e + e − → ωπ 0 and ωη process, no structure is found on the cross section line shape [8].…”
