摘要：
The masses of the excited heavy tetraquarks with hidden charm are calculated within the relativistic diquark–antidiquark picture. The dynamics of the light quark in a heavy–light diquark is treated completely relativistically. The diquark structure is taken into account by calculating 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(4260), Y(4360), Z(4248), Z(4433) and Y(4660) could be tetraquark states with hidden charm.
