Measurement of gA and gv, the neutral current coupling constants to leptons

Description

We have measured both the rates and the forward-backward asymmetry of l+l- from Zdeg→l+l- (where l=μ, τ) with the L3 detector. We obtained Γll=88±4±3 MeV and the vector neutral current coupling constant, gv=0.00±0.07 and the axial vector neutral current coupling constant, gA=-0.515±0.015. (orig.)
