Magnetic Moments of Baryons with a Heavy Quark

We compute magnetic moments of baryons with a heavy quark in the bound state approach for heavy baryons. In this approach the heavy baryon is considered as a heavy meson bound to a light baryon. The latter is represented as a soliton excitation of light meson fields. We obtain the magnetic moments by sandwiching pertinent components of the electromagnetic current operator between the bound state wave–functions. We extract this current operator from the coupling to the photon field after extending the action to be gauge invariant.
