Black hole 2-2 Eikonal scattering is currently well understood both by ‘t Hooft’s semiclassical S-matrix and its field theoretic formulation. However upon attempting to resum our amplitude over partial waves an apparent mismatch occurs. In this talk we will review our formalism applied to elastic scattering. We will showcase the new partial wave resummation, and solve the mismatch by generalizing the 2-2 Eikonal to many particles. This alters the interpretation of our previous result in comparison to ‘t Hooft’s. Additionally we will speculate on the possibility to model EMRI’s within our formalism, since it allows for calculating radiative Feynman diagrams.
