Study of the spectra and decay widths of singly heavy baryons

We present a study of the spectra and strong decay widths of singly heavy baryons. The masses of singly heavy baryons up to the D-wave are calculated within a constituent quark model, employing the three-quark and quarkdiquark schemes. In this contribution, we discuss the possible assignment of the recently discovered Ω c (3327) 0 , Ξ b (6327) 0 , and Ξ b (6333) 0 as D-wave excited states in the charm and bottom sectors, respectively. Additionally, we discuss why the presence or absence of the ρ-mode excitations in the experimental spectrum is the key to distinguishing between the quark-diquark and three-quark behaviors.
