Description
Masses of the triply heavy tetraquarks of all flavor contents are calculated within the relativistic quark model, based on the quasipotential approach and QCD, and diquark--antidiquark picture of tetraquarks. The relativistic quasipotential equation takes into account all spin-dependent and spin-independent relativistic corrections and the internal structure of the diquarks. The calculated masses of such tetraquarks are compared with the strong fall--apart decay thresholds into a heavy and heavy--light mesons. The states that could be observed as narrow resonances in other decay modes are determined.
