Study of the process $e^+e^-\to π^+π^-π^0η$ in the c.m. energy range 1394--2005 MeV with the CMD-3 detector

Abstract

The cross section of the process $e^+e^- \to π^+π^-π^0η$ has been measured using a data sample of 21.8 pb$^{-1}$ collected with the CMD-3 detector at the VEPP-2000 $e^+e^-$ collider. 2769$\pm$95 signal events have been selected in the center-of-mass energy range 1394--2005 MeV. The production dynamics is dominated by the $ω(782)η$ and $ϕ(1020)η$ intermediate states in the lower energy range, and by the $a_0(980)ρ(770)$ intermediate state at higher energies.
