Abstract content <br> (Max 300 words)
We are interested in the soliton description of baryons with a single heavy quark (charm or bottom). In this approach such baryons emerge as composites of a soliton of mesons built from light quarks (up, down, strange) and a meson field that is bound to the soliton and contains a heavy quark. The soliton must then be quantized as a diquark because the fermionic character arises from binding to the heavy meson field. We are particularly interested in baryons that contain strange flavors; in the quark model that corresponds to, say, up-strange-bottom. Thus the flavor symmetry breaking among the light quarks must be incorporated when constructing diquark states. Here we present computations of the diquark eigen-energies and eigen-functions that incorporates all orders of the light flavor symmetry breaking. We also compare these results to a leading order treatment of flavor symmetry breaking. This is a first step towards a comprehensive description of heavy baryons in a soliton model.
