Abstract We show that longitudinal polarization of the outgoing lepton in e + e − →μ + (τ + )μ − (τ − ) is expected at the energies of a vector meson resonance (Ψ, ϒ, T, …). On the basis of the standard SU(2) × U(1) theory, this parity violating observable is already appreciable (∼3%) for the ϒ, and it becomes ∼9% for a T at 30 GeV.
