Abstract

In a semibosonized SU(3) Nambu-Jona-Lasinio model explicit symmetry breaking mass terms are introduced. The soliton solution corresponding to an isospin embedding of the SU(2) hedgehog in the SU(3) group is studied. The hyperon splittings and the hadronic part of the isospin mass differences are calculated and a good agreement with experiment is found.
