Abstract

Within the collective coordinate approach to chiral soliton models we suggest that breaking of SU(3) flavor symmetry mainly resides in the baryon wave-functions while the charge operators have no (or only small) symmetry breaking components. In this framework we study the g_A/g_V ratios for hyperon beta-decay as well as the various quark flavor components of the axial charge of the nucleon and the Λ-hyperon.
