摘要：
Heavy tetraquark states are studied within the diquark-antidiquark picture in the framework of a simple constituent quark model. Considering hyperfine spin and isospin interactions, we predict the masses of the scalar diquarks and of the open and hidden charmed and bottom scalar tetraquarks. Our results indicate the scalar resonances D-0*(2400) and D-s(2632) have a sizable tetraquark amount in their wave function, while it turns out the scalar state D-s0*(2317) should not be considered as being predominately diquark-antidiquark bound states.
