Triply charmed and bottom baryons in a constituent quark model

Abstract

In this work, we study the mass spectrum of the ${\Omega }_{ccc}$ and ${\Omega }_{bbb}$ baryons up to the $N=2$ shell within a nonrelativistic constituent quark model (NRCQM). The model parameters are adopted from the determinations by fitting the charmonium and bottomonium spectra in our previous works. The masses of the ${\Omega }_{ccc}$ and ${\Omega }_{bbb}$ baryon states predicted in present work reasonably agree with the results obtained with the Lattice QCD calculations. Furthermore, to provide more knowledge of the ${\Omega }_{ccc}$ and ${\Omega }_{bbb}$ states, we evaluate their radiative decays with the available masses and wave functions from the potential model.
