Scientific paper

We study certain physical observables of isoscalar heavy baryons using potential models based on hadronic degrees of freedom. The goal is to compare these results with those from an effective theory obtained in a combined heavy quark and large $N_{c}$ expansion and thereby test the convergence of the effective theory. We study the excitation energy of $\Lambda_{b}$ and semileptonic decay form factors. The models tend to confirm the usefulness of the effective theory for most observables.
