We report progress on calculations of the heavy–light baryons Σ c and Λ 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. [ABSTRACT FROM AUTHOR]
