Spectroscopy and radiative decays of Ω ccc and Ω bbb baryons in a quark–diquark model

We present a comprehensive study of the spectra and radiative decays of the triply heavy baryons Ω ccc Ω ccc and Ω bbb Ω bbb within a quark–diquark framework using a 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 mass spectra together with E1/M1 decay widths for radially and orbitally excited states, and systematically compare our results with those from other theoretical approaches.
