Description

The reaction $e^{+}{e}^{-}\to {\pi }^{+}{\pi }^{-}{\pi }^0\eta$ has been studied in the experiment with the SND detector at the VEPP-2000 $e^{+}{e}^{-}$ collider. The reaction proceeds via the four intermediate states: $\omega \eta$, $\varphi \eta$, $a_0\rho$ and structureless ${\pi }^{+}{\pi }^{-}{\pi }^0\eta$ state, which may be, for example, $\rho (1450)\pi$ with $\rho (1450)\to \rho (770)\eta$. The total $e^{+}{e}^{-}\to {\pi }^{+}{\pi }^{-}{\pi }^0\eta$ cross section and cross section for the four intermediate states have been measured and fitted in the vector meson dominance model.
