Description
Scattering of heavy compact objects is an important process in gravitational physics which has recently attracted interest from different communities including numerical relativity and the approach based on the graviational self-force.
In the weak field limit methods from perturbation theory are admissible. In this context, the amplitudes-based framework has been instrumental in pushing the state of the art to the fourth order in perturbation theory.
In this talk I will discuss recent efforts and challenges in extending these results to the next order in perturbation theory. In particular, I will present a computation in electrodynamics which marks an important step towards the ultimate goal of computing observables for gravitational scattering at the fifth order in Newton's constant.
