THE CONSTITUENT QUARK AS A SOLITON IN A LINEAR SIGMA-MODEL

We study a stable, soliton-like solution in the linear sigma-model whe re the chiral fields are coupled to a single massless nonstrange quark . We investigate a possibility that this solution represents the const ituent quark of Georgi and Manohar. We show that its properties are in deed consistent with nucleon observables. Furthermore, we derive chira l meson exchange potentials between such objects which are similar to recently used potentials in the constituent quark models.
