The method of phenomenological nonlinear Lagrangians is described in detail for the case of chiral SU (2) (2). The complete nonlinear Lagrangian is constructed for a theory of pions, nucleons, and vector and axial-vector mesons. The Lagrangian allows a study of the strong and weak interactions of the particles involved. Relations between masses and coupling constants emerge. A model containing only pions and nucleons is also described. Finally, the way to generalize the method to SU (3) (3) is indicated.
