Effective Chiral Meson-Baryon Lagrangian from Path Integral Hadronization of a Quark-Diquark Model
Dietmar Ebert, Thomas Jurke
Abstract
The approach of path integral hadronization, applied to a quark-diquark toy model, is used to derive an effective chiral meson-baryon Lagrangian. In this approach the Goldberger-Treiman relation, found at the quark-meson level, is re-established at the composite hadron level. For illu- strations, electromagnetic low energy characteristics of composite nucleons are estimated.
