Measurement of the weak-neutral-current coupling constants of the electron and limits on the electromagnetic properties of the muon neutrino

Abstract

The weak coupling constants of the electron, ${g}_{V}^{e}$ and ${g}_{A}^{e}$, are determined from measurements of the total and differential cross sections for the reaction ${\ensuremath{\nu}}_{\ensuremath{\mu}}$e\ensuremath{\rightarrow}${\ensuremath{\nu}}_{\ensuremath{\mu}}$e. The data also place limits of interest on the magnitudes of a neutrino charge radius and a possible neutrino magnetic dipole moment.
