Résumé : The Caswell-Wilczek analysis on the gauge dependence of the effective action and the renormalization group functions in Yang-Mills theories is generalized to generic gauge theories including higher dimensional operators. It is shown that the physical coupling constants of the classical theory can be redefined by gauge parameter dependent contributions of higher orders in ħ in such a way that the effective action depends trivially on the gauge parameters, while suitably defined physical beta functions do not depend on those parameters. © 2000 The American Physical Society.
