Description
In recent years, techniques from perturbative quantum field theory have driven significant progress in the Post-Minkowskian (PM) expansion of binary black hole dynamics. A key challenge in this framework arises from conservative, nonlocal-in-time contributions, which obstruct a straightforward analytic continuation from scattering states to bound orbits via the boundary-to-bound (B2B) dictionary. In this talk, I will present a practical resolution based on a hybrid subtract-and-add scheme that consistently combines PM, Post-Newtonian (PN), and self-force (SF) results. This approach enables the controlled treatment of nonlocal effects and yields new state-of-the-art results for the conservative dynamics at 5PM order, including contributions up to 10th order in the self-force expansion.
