Description
The high-statistical KLOE data on the φ→π0π0γ decay are described simultaneously with the data on the ππ scattering and the ππ→KK reaction. The description is carried out taking into account the chiral shielding of the putative σ(600) meson and its mixing with the well-established f0(980) meson. It is shown that the data do not contradict the existence of the σ(600) meson and yield evidence in favor of the four-quark nature of the σ(600) and f0(980) mesons
