Abstract The Goldberger-Treiman relation between the pion decay amplitade and the axial vector coupling constant in B decay is shown to be plausible if the divergence of the axial vector current is a highly nonsingular operator (i.e., one that emphasizes low frequencies). Such a situation is probably realized in a renormalizable theory for which this operator is proportional to the conventional pion field. Some other possible consequences of the low-frequency character of the operator are mentioned. (auth)
