Masses of Ground States of Triply Heavy Tetraquarks

Masses of ground states of triply heavy tetraquarks are calculated within the relativistic quark model based on the quasipotential approach and the diquark–antidiquark picture of tetraquarks. The relativistic diquark–antidiquark interaction quasipotential takes into account the internal structure of the diquark and antidiquark and all relativistic corrections. The calculated masses are compared to fall-apart decay thresholds into a meson pair, and conclusions are drawn about the possibility of detecting such states.
