Аннотация:Masses of the ground-state light tetraquarks are dynamically calculated in the framework of the relativistic diquark-antidiquark picture. The internal structure of the diquark is taken into account by calculating the form factor of the diquark-gluon interaction in terms of the overlap integral of the diquark wave functions. It is found that scalar mesons with masses below 1 GeV, f(0)(600) (sigma), K-0*(800) (kappa), f(0)(980) and a(0)(980), agree well with the light-tetraquark interpretation.
