The eikonal approach to gravitational scattering and radiation at $ \mathcal{O} $(G$^{3}$)
Using $ \mathcal{N} $ = 8 supergravity as a theoretical laboratory, we extract the 3PM gravitational eikonal for two colliding massive scalars from the classical limit of the corresponding elastic two-loop amplitude. We employ the eikonal phase to obtain the physical deflection angle and to show how...
