“Asymptotic symmetries: higher spins and higher dimensions”

The interplay between asymptotic symmetries and their observable counterparts, soft theorems and memory effects, has recently drawn renewed attention on the asymptotic properties of gauge theories near null infinity. We present recent developments in the analysis of such properties for higher dimensions and for theories possessing fields with arbitrary integer spin. Our discussion is mainly motivated by the fact that Weinberg’s soft theorem holds for arbitrary spins and dimensions. In this context, we focus on the possibility of introducing infinite-dimensional asymptotic symmetries whose Ward identities give rise to the soft theorem, compatibly with the finiteness of physical observables at infinity, and residual symmetries which are suited to the interpretation of memory effects as vacuum transitions.
