Measurement of the $e^{+}{e}^{-}\to {\pi }^{+}{\pi }^{-}{\pi }^0\eta$ cross section below $\sqrt{s}=2$ GeV

The process $e^{+}{e}^{-}\to {\pi }^{+}{\pi }^{-}{\pi }^0\eta$ is studied in the center-of-mass energy region below 2 GeV with the SND detector at the VEPP-2000 $e^{+}{e}^{-}$ collider. The four intermediate states contribute to this process: $\omega \eta$, $\varphi \eta$, $a_0(980)\rho$, and a structureless ${\pi }^{+}{\pi }^{-}{\pi }^0\eta$ state. We measure the total $e^+e^- \to \pi^+\pi^-\pi^0\eta$crosssectionandthecrosssectionsforitscomponents:$\omega\eta$,$\phi\eta$,andasumof$a_0(980)\rho$ and the structureless state. Our results are in agreement with previous measurements and have comparable or better accuracies.
