Heavy baryon spectroscopy in a quark-diquark approach

Abstract

We report progress on calculations of the heavy-light baryons $\hat{I}{\pounds }_c$ and $\hat{I}{›}_c$ and their excitations with $J^P=1/2^{+}$ using functional methods. We employ a covariant quark-diquark approach, where the interaction amounts to a quark exchange between quarks and diquarks and the ingredients are determined from the quark level. A partial-wave analysis reveals the presence of orbital angular momentum components in terms of p waves, which are non-relativistically suppressed.
