Asymptotic symmetries in (d + 2)-dimensional gauge theories

Asymptotic symmetries in (d + 2)-dimensional gauge theories

Abstract We show that the subleading soft photon theorem in a (d + 2)-dimensional massless abelian gauge theory gives rise to a Ward identity corresponding to divergent large gauge transformations acting on the celestial sphere at null infinity. We further generalize our analysis to (d + 2)-dimensio...
