  Abstract:
The partial width of the decay channels f0(500) → ππ, f0(980)→ ππ and f0(980) → K K 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 |H〉 = ([su][s u]+[sd][s d])/√2 and light |L〉 = [ud][u d] scalar diquark-antidiquark components. Obtained results for the full width of the f0(500) meson Γth.=408.8±84.8  MeV and for the f0(980) meson Γth.=34.71±7.26MeV are compared with the world averages for these parameters, and a reasonable agreement between them is found.
