Scattering Amplitudes, the Tail Effect, and Conservative Binary Dynamics at $O(G^4)$

Zvi Bern, Julio Parra-Martinez, Radu Roiban +4

We complete the calculation of conservative two-body scattering dynamics at fourth post-Minkowskian order, i.e. $O(G^4)$ and all orders in velocity, including radiative contributio…
