Abstract

Abstract In this contribution we describe computational tools that permit the evaluation of multi‐loop scattering amplitudes in 𝒩 = 8 supergravity, in terms of amplitudes in 𝒩 = 4 super‐Yang‐Mills theory. We also discuss the remarkable ultraviolet behavior of 𝒩 = 8 supergravity, which follows from these amplitudes, and is as good as that of 𝒩 = 4 super‐Yang‐Mills theory through at least four loops.
