摘要：

The partial width of the decay channels f(0)(500) ->pi pi, f(0)(980) -> pi pi and f(0)(980) -> K (K) over bar are calculated using QCD light-cone sum rules method and a technique of the soft meson approximation. The scalar particles are treated as mixtures of the heavy vertical bar H > =([su][(s) over bar (u) over bar] +[sd][(s) over bar(d) over bar])/root 2and light vertical bar L > =[ud][(u) over bar(d) over bar] scalar diquark-antidiquark components. Obtained results for the full width of the f(0)(500) meson Gamma(th) = 434.7 +/- 72.3MeVand for the f(0)(980) meson Gamma(th)= 42.12 +/- 6.70MeVare compared with the world averages for these parameters, and a reasonable agreement between them is found.
