Asymptotic symmetries and Weinberg’s soft photon theorem in Mink d+2
Abstract We show that Weinberg’s leading soft photon theorem in massless abelian gauge theories implies the existence of an infinite-dimensional large gauge symmetry which acts non-trivially on the null boundaries ± of (d + 2)-dimensional Minkowski spacetime. These symmetries are parameterized by an...
