Abstract
We study the possibility that vector-boson self-couplings may differ from their standard model values. We find that known constraints from loop effects and from unitary already imply that such deviations are of order 10 −2 or less. Consequently, even if the correct model differs from the standard model and even if the energy scale of new physics is as low as 1 TeV, a direct observation of anomalous couplings is very imporabable in the LEP-200 and Tevatron experiments.
