Abstract
We present a comprehensive study of the spectra and radiative decays of the triply heavy baryons $\Omega_{ccc}$ and $\Omega_{bbb}$ within a quark-diquark framework using a relativistic screened potential model. The analysis is carried out by solving a relativized Hamiltonian for a two-body bound system: the diquark masses are first determined, after which each baryon is treated as a composite of the diquark and the third quark. Employing the obtained wave functions, we calculate electromagnetic transitions using the E1 and M1 operators. We report complete $N_{d} L_{d} n_{q} l_{q}$ spectra together with E1/M1 decay widths for radially and orbitally excited states, and systematically compare our results with those from other theoretical approaches.
