Sažetak
SU(3)-symmetry breaking is studied in the framework of the chiral bag models. Comparisons are also made with the MIT bag model and the harmonic-oscillator quark model. An important clue for the nature of the symmetry breaking comes from the isoscalar axial-vector coupling constant gSA which can be indirectly estimated from the Bjorken sum rules for deep- inelastic scattering. The chiral bag model with two radii reasonably well accounts for the empirical values of gSA and of the axial-vector coupling constants measured in hyperon semileptonic decays.
