摘要：
The relativistic model of heavy tetraquarks is formulated within the diquark-antidiquark picture. The diquark structure is taken into account by the diquark-gluon form factor. New experimental data on charmonium-like states above open charm threshold are discussed. The obtained results indicate that X(3872), Y(4140), Y(4260), Y(4360), Z2(4250), Z(4433) and Y(4660) could be tetraquark states with hidden charm. Predictions for the masses of bottom counterparts to the charm tetraquark candidates are given.
