Strongly Distorted Baryon Wave-Functions: Hyperon Beta-Decay and the Spin of the Lambda and the Nucleon

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 $\Lambda$-hyperon.
