Born cross sections for the processes $e^+e^- \to \omega\eta$ and $e^+e^- \to \omega\pi^{0}$ have been determined for center-of-mass energies between 2.00 and 3.08 GeV with the BESIII detector at the BEPCII collider. The results obtained in this work are consistent with previous measurements but with improved precision. Two resonant structures are observed. In the $e^{+}e^{-} \to \omega\eta$ cross sections, a resonance with a mass of $(2179 \pm 21 \pm 3)\text{MeV}/c^2$ and a width of $(89 \pm 28 \pm 5)\text{MeV}$ is observed with a significance of 6.1$\sigma$. Its properties are consistent with the $\phi(2170)$. In the $e^{+}e^{-} \to\omega\pi^{0}$ cross sections, a resonance denoted $Y(2040)$ is observed with a significance of more than 10$\sigma$. Its mass and width are determined to be $(2034 \pm 13 \pm 9)\text{MeV}/c^2$ and $(234 \pm 30 \pm 25)\text{MeV}$, respectively, where the first uncertainties are statistical and the second ones are systematic.

在 2.00 到 3.08 GeV 的质心能量下观察 e+e− → ωη 中的共振结构和 e+e− → ωπ0 中的另一个共振结构

过程 $e^+e^- \to \omega\eta$ 和 $e^+e^- \to \omega\pi^{0}$ 的出生横截面已确定为2.00 和 3.08 GeV，在 BEPCII 对撞机上使用 BESIII 检测器。在这项工作中获得的结果与以前的测量结果一致，但精度有所提高。观察到两种共振结构。在 $e^{+}e^{-} \to \omega\eta$ 截面中，共振质量为 $(2179 \pm 21 \pm 3)\text{MeV}/c^2$ 和观察到的宽度为 $(89 \pm 28 \pm 5)\text{MeV}$，显着性为 6.1$\sigma$。其性质与$\phi(2170)$一致。在 $e^{+}e^{-} \to\omega\pi^{0}$ 截面中，观察到表示为 $Y(2040)$ 的共振，其显着性超过 10$\sigma$。
