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 $O(N_c^{-1}\cdot m_{\hat{I}}{¦}^0)$ where $m_{\hat{I}}¦$ is the mass of the heavy-meson (isospin) doublet $\hat{I}¦$ or $\hat{I}{¦}^{\ast }$.
