摘要：

The approach of path integral hadronization is applied to an SU(2) model of quark-diquark flavor dynamics. Within such a scheme we derive an effective chiral meson-baryon Lagrangian, where the Goldberger-Treiman relation, found earlier at the quark-meson level, is now reestablished at the composite hadron level. Masses and coupling constants of composite hadrons are then calculable by the parameters of the underlying microscopic quark-diquark picture. [S0556-2821(98)00115-5]
