Abstract
Preliminary data on the reactions e(+) e(-) --> phi --> gamma f(0)(980 ) --> gamma pi(0) pi(0) together with data on rr pi pi scattering and the reactions J/psi --> phi pi(+)pi(-) and K(-)p --> pi(+)pi(-) (Lambd a,Sigma) are analyzed. The analysis shows that the mass of the f(0)(98 0) meson is m(f0) = 950 MeV, and BR(phi --> gamma f(0) --> gamma pi(0) pi(0)) similar or equal to 1 x 10(-4), indicating that the f(0)(980) resonance is of a four-quark nature.
