Study of the process $e^{+}{e}^{-}\to \omega \eta {\pi }^0$ in the energy range $\sqrt{s}<2$ GeV with the SND detector

Abstract

The process $e^{+}{e}^{-}\to \omega \eta {\pi }^0$ is studied in the energy range $1.45-2.00$ GeV using data with an integrated luminosity of 33 pb${}^{-1}$ accumulated by the SND detector at the $e^{+}{e}^{-}$ collider VEPP-2000. The $e^{+}{e}^{-}\to \omega \eta {\pi }^0$ cross section is measured for the first time. The cross section has a threshold near 1.75 GeV. Its value is about 2 nb in the energy range $1.8-2.0$ GeV. The dominant intermediate state for the process $e^{+}{e}^{-}\to \omega \eta {\pi }^0$ is found to be $\omega a_0(980)$.
