Title: Application of invariant renormalization to the non-linear chiral invariant pion Lagrangian in the one-loop approximation
Abstract: The functional for the one-loop diagrams for the non-linear chiral invariant pion Lagrangian is calculated invariantly using methods strongly reminiscent of gauge-invariant renormalization techniques in QED. It is shown that the restrictions chiral invariance puts on the renormalization counterterms do not suffice to extract finite results from the one-loop diagrams. The problem of the Adler condition in the presence of a symmetry breaking mass term is considered.
