Yukawa coupling constants for the baryon decuplet and octet

초록

In this talk, we present the recent results on the Yukawa coupling constants for the baryon decuplet and octet, based on a general framework of a chiral soliton model, taking into account the flavor SU(3) symmetry breaking and isospin symmetry breaking. All relevant dynamical variables are determined by the experimental data for hyperon semileptonic decays and the singlet axial-vector constant of the nucleon. We emphasize the coupling constants for the multi-strangeness hyperons.
