Electromagnetic Induction of Neutral Lepton Currents

Abstract

We have considered the induction of neutral lepton currents in the weak interaction Lagrangian through the mediation of the electromagnetic field. These considerations are within the framework of the conventional picture in which neutral lepton currents are conspicuous by their absence. Our motivation, in fact, derives from the need to establish the relevance, or irrelevance, of any conceivable physical observation of these currents to a theory of weak interactions. The couplings associated with both the vector and axial vector lepton currents are investigated in a simple model. We also consider some physical processes that may be expected to carry the signature of neutral lepton currents.
