Description

We present a study on single heavy baryons' spectra and strong decay widths. The masses of single heavy baryons up to the D-wave are calculated within a constituent quark model, employing the three-quark and quark-diquark schemes. In this contribution, we discuss the possible assignment of the recently discovered ${\mathrm{\Omega }}_c^0(3327)$, ${\mathrm{\Lambda }}_b(6146{)}^0$, ${\mathrm{\Lambda }}_b(6152{)}^0$, ${\mathrm{\Xi }}_b(6327{)}^0$, and ${\mathrm{\Xi }}_b(6333{)}^0$ as D-wave excited states in the charm and bottom sectors, respectively. Additionally, we discuss the ${\mathrm{\Lambda }}_b(6070{)}^0$ assignment and why the presence or absence of the $\rho$-mode excitations in the experimental spectrum is the key to distinguishing between the quark-diquark and three-quark behaviors.
