The gravitational S-matrix: from theory to experiment

Recent insights into the gravitational S-matrix, which describes the scattering of gravitating particles, have lead to a breakthrough in the perturbative understanding of the two-body problem in General Relativity, with direct relevance to gravitational wave physics. Such advances have been enabled by the methods of scattering amplitudes and effective field theory, originally developed in the context of particle and collider physics. Despite recent progress, a formalism to extract the dynamics of inspiralling compact binaries from scattering amplitudes is still lacking, in order for the results of this program to be fully implemented in the analysis of gravitational wave data. Furthermore,…
