Description
We present a study of the spectra and strong decay widths of heavy baryons. The masses of single heavy baryons up to the D-wave are calculated within a constituent quark model, employing both the three-quark and quark-diquark schemes. We calculated the decay widths of the ground and excited single heavy baryons into the charmed baryon-(vector/pseudoscalar) meson pairs and the (octet/ decuplet) baryon-(pseudoscalar/vector) charmed meson pairs. Moreover, we discuss 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, as was originally pointed out in [1].
Our quantum number assignments and predictions for mass spectra and strong-decay widths are in agreement with the available data. Hence, our findings provide valuable guidance for future measurements in experiments conducted at LHC, Belle, and Belle II.
