Christoph Burmann,Julia LaunspachThe momentum space cutoff we have been using is the most intuitive form of regularization, but it is not the most efficient one. For a scalar field theory which does not have any gauge symmetries to preserve it is fine. But in a gauge theory, the momentum space cutoff is bad news.

B S Johnson and Post-War LiteratureSometimes a symmetry which seems to be present in a theory at the classical level can be spoiled by quantum (loop) effects. We have already seen such an example without knowing it.

B. Traven – Die unbekannten JahreWe have dealt with the simplest kind of gauge theory, which is based on the gauge symmetry .(1). It is an Abelian group because any two .(1) transformations commute with each other:
