    "abstract": "A simple $\\pi \\pi$, $\\bar{K}K$, and $\\rho \\rho$($\\omega \\omega$) fully\ncoupled channel model is proposed to predict the isoscalar S-wave phase shifts\nand inelasticities for $\\pi \\pi$ scattering in the 1.0 to 2.0 GeV region. The\nS-matrix is required to exhibit poles corresponding to the established\nisoscalar J$^{\\pi}$ = 0$^+$ resonances f$_0$(975), f$_0$(1400), and\nf$_0$(1710). A dominant feature of the experimental $\\pi \\pi$ inelasticity is\nthe clear opening of the $\\bar{K}K$ channel near 1 GeV, and the opening of\nanother channel in the 1.4 - 1.5 GeV region. The success of our model in\npredicting this observed dramatic energy dependence indicates that the effect\nof multi-pion channels is adequately described by the $\\pi \\pi$ coupling to the\n$\\bar{K}K$ channel, the $\\rho \\rho$(4$\\pi$) and $\\omega \\omega$(6$\\pi$)\nchannels.",
