Gravitational Bremsstrahlung in the Post-Minkowskian expansion

I will discuss the scattering of two compact objects interacting via gravity, using the so-called world-line Effective Field Theory approach in the post-Minkowskian expansion (i.e. expanding in the Newton's constant G but not in the velocities). In particular, I will focus on the computation of classical observables such as the total emitted momentum. This is obtained by phase-space integration of the graviton momentum weighted by the modulo squared of the radiation amplitude. It can be recast as an effective cut two-loop integral that I will solve using techniques borrowed from collider physics.
