dc.descriptionIn combined 2- and 3-channel analyses of experimental data on the coupled processes $ππ\toππ,K\bar{K},ηη$ in the channel with $I^GJ^{PC}=0^+0^{++}$, various scenarios of these reactions(with different numbers of resonances) are considered. In a model-independent approach, confirmation of the $σ$-meson below 1 GeV and definite indications of the QCD nature of other $f_0$ resonances are obtained. The conclusion on the linear realization of chiral symmetry is drawn.
