Asymptotic charges in massless QED revisited: a view from spatial infinity
Hamada and Shiu have recently shown that tree level amplitudes in QED satisfy an in nite hierarchy of soft photon theorems, the rst two of which are Weinberg and Low's theorems respectively. In this paper we propose that in tree level massless QED, this entire hierarchy is equivalent to a hierarchy...
