| Abstract: | The chiral invariant σ-model is used to obtain bound states (solitons) of valence quarks. A hedgehog shape is assumed for the pion field. A soluble model is presented and compared to a self-consistent calculation. The results are discussed in the light of the possible effective baryon number carried by the chiral fields. |
