2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/178814Using LEP1, SLD and LEP2 data, for tau lepton production, and data from CDF, D0 and LEP2, for W decays into tau leptons, we set model independent limits on non-standard electromagnetic and weak magnetic moments of the tau lepton. The most general effective Lagrangian giving rise to tau moments is used without further assumptions. Precise bounds ($2σ$) on the non-standard model contributions to tau electromagnetic ($-0.007<a_γ< 0.005$), tau Z-magnetic ($-0.0024 <a_Z< 0.0025$) and tau W-magnetic ($-0.003 < κ^W < 0.004$) dipole moments are set from the analysis.19 pages, 2 figures, elsart.sty.
