Abstract

The Born cross sections for the process e⁺e⁻→ ωη^ are measured at 22 center-of-mass energies from 2.000 to 3.080 GeV using data collected with the BESIII detector at the BEPCII collider. A resonant structure is observed 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.
