Title: Properties of the light scalar mesons face the experimental data on the {phi}{yields}{pi}{sup 0}{pi}{sup 0}{gamma} decay and the {pi}{pi} scattering

Abstract

The high-statistical KLOE data on the {phi}{yields}{pi}{sup 0}{pi}{sup 0}{gamma} decay are described simultaneously with the data on the {pi}{pi} scattering and the {pi}{pi}{yields}KK reaction. The description is carried out taking into account the chiral shielding of the putative {sigma}(600) meson and its mixing with the well-established f{sub 0}(980) meson. It is shown that the data do not contradict the existence of the {sigma}(600) meson and yield evidence in favor of the four-quark nature of the {sigma}(600) and f{sub 0}(980) mesons.
