Study of the process $e^{+}{e}^{-}\to \eta \gamma$ in the center-of-mass energy range 1.07--2.00 GeV

Abstract

The $e^{+}{e}^{-}\to \eta \gamma$ cross section has been measured in the center-of-mass energy range 1.07--2.00 GeV using the decay mode $\eta \to 3{\pi }^0$, ${\pi }^0\to \gamma \gamma$. The analysis is based on 36 pb${}^{-1}$ of integrated luminosity collected with the SND detector at the VEPP-2000 $e^{+}{e}^{-}$ collider. The measured cross section of about 35 pb at 1.5 GeV is explained by decays of the $\rho (1450)$ and $\varphi (1680)$ resonances.
