The strong decays of the light scalar mesons f0(500) and f0(980)
The partial width of the decay channels f0(500)→ππ, f0(980)→ππ and f0(980)→KK¯ 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...
