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 quark-diquark schemes. In this contribution, we discuss the possible assignment of the recently discovered ¿
c (3327)0, ¿b (6327)0, and ¿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 ¿-mode excitations in the experimental spectrum is the key to distinguishing between the quark-diquark and three-quark behaviors. © The Authors, published by EDP Sciences.
