Abstract

A pure weak interaction such as muon decay μev \(\overline{v}\) is characterized by a V-A amplitude. When hadrons participate the strong force induces additional couplings and the reaction is classified as semi-leptonic. These additional couplings are real due to time reversal invariance. The scalar and tensor couplings are expected to vanish because these currents have the wrong G-parity and experimentally non-zero values have not been found. In beta decay npe \(\overline{v}\) the renormalized axial vector strength, g a , and the weak magnetism strength, g m , which is predicted by CVC, are accurately measured.
