The phi(1020) ---> pi0 pi0 gamma decay

In the SND experiment at VEPP-2M e + e − collider the φ (1020)→ π 0 π 0 γ decay was studied and its branching ratio was measured: B ( φ → π 0 π 0 γ )=(1.221±0.098±0.061)·10 −4 . It was shown, that f 0 (980) γ intermediate state dominates in this decay and the f 0 (980)-meson parameters were obtained.
