Abstract
The parity violating but CP conserving anomalous three-gauge-boson coupling induces a universal contribution to the left-handed coupling of the boson to fermions. We find that the LEP measurements of the partial widths and lepton forward-backward asymmetries are sufficiently precise to place a bound of order less than . This bound is significantly better than what can be obtained at present from rare and meson decays.
