The mixing angle, mass and couplings of the light scalar mesons f0(500) and f0(980) are calculated in the framework of QCD two-point sum rule approach by assuming that they are tetraquarks with diquark–antidiquark structures. The mesons 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. We extract from corresponding sum rules the mixing angles φH and φL of these states and evaluate the masses and couplings of the particles f0(500) and f0(980)
