Conserved currents in the theory of Fermi interactions

Abstract

Feynman and Gell-Mann (1) have proposed a scheme in which the vector Fermi interactions are described in terms of an interaction with itself of a vector current. In a similar way the axial vector coupling may be thought of as a self interaction of an axial vector current. Furthermore, they propose to add strangeness-violating terms to these currents in order to account for strange particle decays.
