Resumen

We 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 M_R = (2153 ± 30 ± 31) MeV/c² and its width to be Γ_R = (167 ± 77 ± 7) MeV, where the first uncertainties are statistical and the second are systematic.
