Study of the process e + e - →ω η π 0 in the energy range √{s }<2 GeV with the SND detector

The process ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}\ensuremath{\omega}\ensuremath{\eta}{\ensuremath{\pi}}^{0}$ is studied in the energy range 1.45--2.00 GeV using data with an integrated luminosity of $33\text{ }\text{ }{\mathrm{pb}}^{\ensuremath{-}1}$ accumulated by the SND detector at the ${e}^{+}{e}^{\ensuremath{-}}$ collider VEPP-2000. The ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}\ensuremath{\omega}\ensuremath{\eta}{\ensuremath{\pi}}^{0}$ 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 ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}\ensuremath{\omega}\ensuremath{\eta}{\ensuremath{\pi}}^{0}$ is found to be $\ensuremath{\omega}{a}_{0}(980)$.
