AbstractWe discuss about the nature of f(0) (400-1200) which we decompose into three parts, i. e., t-channel rho meson and f(2) (1270) meson exchange plus an additional s-channel resonance f(0) (X). Below 1.2GeV of pipi invariant mass, t -channel rho meson exchange can explain the I = pipi S-wave scattering very well. However, the f(2) (1270) meson exchange must be considered for the pipi invariant mass above 1.2GeV. With the t-channel p meson and f(2) (1270) meson exchange fixed by the isotensor pipi-->pipi S-wave scattering, we re-fit the CERN-Mulich(CM) data on pipi scattering to get parameters for the f(0) ( X). We find that it is necessary to introduce a broad 0(++) resonance with a pole about 1.6-1.7GeV.
