Beschreibung
Zusammenfassung:	A bstract The Born cross sections of the processes e + e − → ωπ 0 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 resonances into the ωπ 0 and ωη final states.
