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

Abstract

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 $e^{+}{e}^{-}\to {\pi }^{+}{\pi }^{-}{\pi }^0\eta$ cross section and the cross sections for its components: $\omega \eta$, $\varphi \eta$, and a sum of $a_0(980)\rho$ and the structureless state. Our results are in agreement with previous measurements and have comparable or better accuracies.
