Neutral current coupling constants from neutrino-electron scattering

This article updates a review [1] on experimental results obtained from studies of neutrino electron scattering and shows in particular the important input from these experiments to the improved knowledge of weak neutral currents and the confirmation of the Standard Model at tree level. Special emphasis is put on recent high precision ye-experiments, whose results on electroweak parameters allow, in combination with precise results obtained at higher Q(2), a test of the Standard Model at the level of higher order corrections.
