Study of the $ρ$ , $ω$ , $ϕ \to η γ \to 7 γ$ Decays with an SND Detector on a VEPP-2M Collider

M. N. Achasov, S. E. Baru, K. I. Beloborodov +25

The $e^{+} e^{-} \to η γ \to 7 γ$ process was studied in the energy range $2 E = 600 \div 1060$ MeV with an SND detector on a VEPP-2M $e^{+} e^{-}$ collider. The decay branching ratios $B(ϕ\toηγ)=(1.343\…
