Abstract

The \ensuremathρ\ensuremathρ scattering has been studied by two groups which both claimed a dynamical generated scalar meson, most likely to be f₀(1370). Here we investigate the influence of coupled channels of pseudoscalar mesons, i.e., \ensuremathπ\ensuremathπ and KK, on this dynamical generated scalar state. With the coupled-channel effect included, the pole and partial decay widths are found to be more close to PDG values for f₀(1500).
