Spectroscopy and Radiative Decays of ${\Omega }_{ccc}$ and ${\Omega }_{bbb}$ Baryons in a Quark-Diquark Model

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 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.

Revised the calculations using the completely symmetrized wavefunctions; spectra, state assignments and spectroscopic classification have been re-evaluated; some figures removed and tables added; updated the Abstract, and Results and Discussion section has been substantially rewritten; Matches version accepted for publication in EPJC
