Title: Measurements of electroweak couplings of the tau lepton at L3
Abstract: We review the current knowledge of the couplings of the $\tau$ lepton to theelectroweak gauge bosons, the W, Z and photon, obtained from the full L3data sample at center-of-mass energies near the Z mass. Measurements ofthe the effective vector and axial-vector weak neutral couplings of the $\tau$, theLorentz structure of the weak charged current, and anomalous couplings ofthe electroweak gauge bosons to the $\tau$ are presented.
