Abstract A simpleππ, $$\bar K$$ K, andρρ(ωω) fully coupled channel model is proposed to predict the isoscalarS-wave phase shifts and inelasticities forππ scattering in the 1.0 to 2.0 GeV region. TheS- matrix is required to exhibit poles corresponding to the established isoscalarJ π=0+ resonancesf 0(975),f 0(1400), andf 0(1710). A dominant feature of the experimentalππ inelasticity is the clear opening of the $$\bar K$$ K channel near 1 GeV, and the opening of another channel in the 1.4–1.5 GeV region. The success of our model in predicting this observed dramatic energy dependence indicates that the effect of multipion channels is adequately described by theππ coupling to the $$\bar K$$ K channel, theρρ(4π) andωω(6π) channels.
