摘要：

Calculations with anomalous trilinear gauge boson vertices have been criticized as overestimates due to a failure to incorporate gauge invariance. We show here that the criticized calculations are gauge invariant, although this symmetry is realized nonlinearly. We instead trace the overestimates to an incorrect treatment of cutoffs in loop diagrams.
