Veneziano Model and Current Algebra: the Hypothesis of Partial Conservation of Axial-Vector Current.

Abstract

A systematic procedure for applying the hypothesis of the partial conservation of the axial-vector current to the Regge-pole models of the Veneziano type is illustrated by a discussion of the matrix element of the axial-vector current for the weak process $A_{\mu }+\pi \to \pi +\pi$. Additional information is obtained which relates the reactions $\pi +\pi \to \pi +\pi$ and $\pi +\pi \to \pi +A_1$.
