Description
Scattering amplitudes can be recovered in the AdS/CFT correspondence from CFT correlation functions by taking an infinite radius limit of the AdS spacetime. In this talk, I will discuss the soft factorization of scattering amplitudes in this limit. We first use `classical soft theorems' to establish that soft photon and soft graviton factors involve inverse AdS radius corrections of the known leading flat spacetime soft factors. We then apply the AdS/CFT correspondence to derive the leading inverse AdS radius corrected soft photon factor from the U(1) Ward identity of a CFT. I'll conclude with a discussion on inverse AdS radius corrections of scattering amplitudes about the flat spacetime limit following ongoing work.
