Triply heavy baryon spectroscopy in the relativistic quark model

Triply heavy baryons are investigated in the framework of the relativistic quark model based on the quark-diquark picture in the quasipotential approach in QCD. Masses of the ground and excited states of the $Ω_{ccc}$, $Ω_{bbb}$, $Ω_{ccb}$ and $Ω_{cbb}$ baryons are calculated. Orbital and radial excitations between the diquark and quark as well as between quarks inside the diquark are considered. The diquark internal structure is consistently taken into account by the form factor of the diquark-gluon interaction expressed through the overlap integral of the diquark wave functions. The detailed comparison with previous calculations is given.
