Description

.

Abstract: Dirac’s action for electrically and magnetically charged particles interacting with the electromagnetic field involves singular Dirac strings which introduce a form of non-locality in the formulation. These are invisible provided they do not intersect charged particle world-lines – this is known as the Dirac veto. It is shown that this system has 1-form generalised symmetries and the Dirac veto can be viewed as a restriction to configurations in which certain anomalies vanish.
