Analysis of preliminary data on e^+e^-toφtoγ f₀(980)toγπ⁰π⁰ reaction

We perform the analysis of the preliminary data on $e^+e^-\to\phi\to\gamma f_0(980)\to\gamma\pi^0\pi^0$ reaction simultaneously with the data on $\pi\pi$ scattering and reactions $J/\psi\to\phi\pi^+\pi^-$ and $K^-p\to\pi^+\pi^-(\Lambda,\Sigma)$. It is found that the $f_0(980)$ meson mass $m_{f_0}=950$ MeV and $B(\phi\to\gamma f_0\to\gamma\pi^0\pi^0)\simeq1\cdot10^{-4}$.
