在1.34—2.00 GeV的质心能量范围内，测量了e^+e^- o omegaeta过程的截面。该分析基于在VEPP-2000 $e^+e^-$对撞机上使用SND探测器收集的数据。测量到的e^+e^- 0是迄今为止最精确的。我们的数据与以前的BABAR测量结果有显著的差异。
The cross section for the process $e^+e^- o omegaeta$ is measured in the center-of-mass energy range 1.34--2.00 GeV. The analysis is based on data collected with the SND detector at the VEPP-2000 $e^+e^-$ collider. The measured $e^+e^- o omegaeta$ cross section is the most accurate to date. A significant discrepancy is observed between our data and previous BABAR measurement.
