Bounding anomalous gauge-boson couplings

We investigate indirect phenomenological bounds on anomalous three-gauge-boson couplings. We do so by systematically determining their one-loop implications for precision electroweak experiments. We find that these loop-induced effects cannot be parametrized purely in terms of the parameters S,T, and U. Like some other authors, we find many cancellations among the loop-induced effects, and we show how to cast the low-energy effective theory …
