Massive-quark baryons as skyrmions

Massive-quark baryons containing one or more charm (c) or bottom (b) quarks are described as massive scalar doublet fields wrapped by the soliton of the light (up and down) flavors. The spin-isospin transmutation that takes place to make the trapped scalar behave like heavy-flavored quarks is analogous to what happens to a scalar doublet in the presence of a t Hooft-Polyakov monopole. The Wess-Zumino term plays a pivotal role here. This model predicts spectra that resemble closely those of quark models. In this paper this feature is interpreted in terms of an induced gauge (or Berry) structure associated with fast and slow degrees of freedom corresponding, respectively, to the massive- and light-flavor quarks involved in the baryon structure
