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:
$\omega\eta$, $\phi\eta$, $a_0\rho$ 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.
