The effective action for spinor fields coupled to Abelian or non-Abelian gauge bosons is examined as a function of a composite or elementary field. Various authors have proposed a classical Lagrangian that may lead to quark confinement, and the question is asked whether such a Lagrangian could be an effective one generated by quantum correction to a more conventional one. It is shown that such a mechanism will not be operative for Abelian theories and speculations are made for non-Abelian ones. © 1975 The American Physical Society.
