摘要：
We study the massive SU(3) Skyrmion model to investigate the flavor symmetry breaking (FSB) effects on the static properties of the strange baryons in the framework of the rigid rotator quantization scheme combined with the improved Dirac quantization one. Both the chiral symmetry breaking pion mass and FSB kinetic terms are shown to improve c, the ratio of the strange-light to light-light interaction strengths, and (c) over bar, that of the strange-strange to light-tight interaction strengths.
