A nonrelativistic quark-diquark model, parameterized via the B_c meson spectrum, predicts ground-state masses near 8.0 GeV for Ω_ccb and 11.0 GeV for Ω_cbb, along with magnetic moments and Regge trajectories.

abstract
In this article, we restudy the mass spectrum of the ground state triply-heavy baryon states with the QCD sum rules by carrying out the operator product expansion up to the vacuum condensates of dimension 6 in a consistent way and preforming a novel analysis. It is the first time to take into account the three-gluon condensates in the QCD sum rules for the triply-heavy baryon states.

Mass spectrum, magnetic moments and Regge trajectories of $\Omega_{ccb}$ and $\Omega_{cbb}$ baryons in the nonrelativistic quark--diquark model
A nonrelativistic quark-diquark model, parameterized via the B_c meson spectrum, predicts ground-state masses near 8.0 GeV for Ω_ccb and 11.0 GeV for Ω_cbb, along with magnetic moments and Regge trajectories.
