Soliton Structure of Heavy Baryons

Abstract

Heavy-quark baryons are described as a bound heavy-meson-soliton system in a Lagrangian that combines chiral symmetry and heavy-quark symmetry. We introduce a ``Wess-Zumino type" term and show that it dominates the binding of a heavy meson to a soliton. The connection between this model and the Callan-Klebanov model is established to $O(N_c^{-1} \cdot m_\Phi^0)$ where $m_\Phi$ is the mass of the heavy-meson (isospin) doublet $\Phi$ or $\Phi^*$.
