Measurement of the $e^+e^- \to \omega\eta$ cross section below $\sqrt{s}=2$ GeV

The cross section of the process e+e-→ωη 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-→ωη cross section is the most accurate to date. A significant discrepancy is observed between our data and previous BABAR measurements.
