2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/48741We review the current knowledge of the couplings of the tau lepton to the electroweak gauge bosons, the W, Z and photon, obtained from the full L3 data sample at center-of-mass energies near the Z mass. Measurements of the the effective vector and axial-vector weak neutral couplings of the $τ$, the Lorentz structure of the weak charged current, and anomalous couplings of the electroweak gauge bosons to the tau are presented.Talk presented at DPF99, 5-9 January, 1999, Los AngelesHigh Energy Physics - Phenomenologytext
