We advocate an effective field theory approach to anomalous couplings. The
effective field theory approach is the natural way to extend the standard model
such that the gauge symmetries are respected. It is general enough to capture
any physics beyond the standard model, yet also provides guidance as to the
most likely place to see the effects of new physics. The effective field theory
approach also clarifies that one need not be concerned with the violation of
unitarity in scattering processes at high energy. We apply these ideas to pair
production of electroweak vector bosons.Comment: 16 pages, 1 figur
