Scattering Amplitudes and Conservative Binary Dynamics at $\mathcal{O}(G^4)$

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

Using scattering amplitudes, we obtain the potential contributions to conservative binary dynamics in general relativity at fourth post-Minkowskian order, $\mathcal{O}(G^4)$. As in pr…
