Abstract
The lightest baryon octet is studied within a covariant and confining Nambu–Jona-Lasinio model. By solving the Poincaré covariant Faddeev equations—including scalar and axialvector diquarks—we determine the baryon octet masses and axial charges for strangeness conserving transitions. For the axial charges the degree of violation of SU(3) flavor symmetry, arising because of the strange spectator quark(s), is found to be no more than 10%.
