Abstract

We study the one-loop corrections in chiral perturbation theory to the and * decays of the pseudoscalar mesons. The latter are divergent, thus requiring the existence of dimension-six terms contributing to the anomalous Lagrangian. Some examples of such terms are given. We also discuss the experimental consequences of the next-to-leading terms. © 1988 The American Physical Society.
