    "abstract": "We use a modified version of the Nambu--Jona-Lasinio model which implements\nthe QCD trace anomaly to calculate the two photons decay width of the glueball\n(f_0(1500)) and of the two scalar mesons (f_0(1370), f_{J=0}(1710)) to which it\nis mixed. We investigate the effect of this mixing over the coupling constants\nof the f_0 states to the quarks.",
