Properties of the light scalar mesons face the experimental data on the $\varphi \to {\pi }^0{\pi }^0\gamma$ decay and the $\pi \pi$ scattering

N. N Achasov, A. V. Kiselev

The high-statistical KLOE data on the $\varphi \to {\pi }^0{\pi }^0\gamma$ decay are described simultaneously with the data on $\pi \pi$ scattering and the $\pi \pi \to K\bar{K}$ reaction. The description is carried…
