The eikonal approach to gravitational scattering and radiation at O $$ \mathcal{O} $$ (G 3)

Abstract Using N $$ \mathcal{N} $$ = 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 an...
