Consequences of a simple phenomenologicalV−Amodel for neutral currents

Abstract
We examine the experimental implications of a simple phenomenological VA model of neutral currents, in which the neutral current belongs to the same generalized isospin triplet as the charged currents with zero Cabibbo angle, and in which the current-current effective Lagrangian describing neutral-current interactions has a different over-all strength from that describing charged-current couplings.
