Abstract
We report progress on calculations of the heavy–light baryons \(\varSigma _c\) and \(\varLambda _c\) 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.
