Possible effects of strong interactions in Feinberg-Pais theory of weak interactions. II

Abstract

In a previous paper, a simplified model was used to study the effects of strong interactions on the weak interaction theory of Feinberg and Pais. In this paper, we use a more general argument, a power count based upon the Ward-Takahashi-Nishijima multimeson vertex function identity, to show that the same conclusion remains valid even when crossed ladder graphs are included. Our conclusion may not apply, however, to the modified program of peratization where W-W scattering plays an essential role.
