Study of the radiative decay $\phi \to \eta \gamma$ with CMD-2 detector

The CMD-2 collaboration Akhmetshin, R.R. ; Anashkin, E.V. ; Banzarov, V.S. ; et al.

Using the $1.9 pb^{-1}$ of data collected with the CMD-2 detector at VEPP-2M the decay mode $\phi \to \eta \gamma$, $\eta \to \pi^+\pi^-\pi^0$ has been studied. The obtained branching ratio is B($\phi \to \eta \gamma) = (1.18 \pm 0.03 \pm 0.06) %$.
