We describe a systematic framework for finding the conservative potential of compact binary
systems with spin based on scattering amplitudes of particles of arbitrary spin and effective …

A bstract We obtain the quadratic-in-spin terms of the conservative Hamiltonian describing
the interactions of a binary of spinning bodies in General Relativity through\(\mathcal {O}\)(G …

We compute the conservative two-body Hamiltonian of a compact binary system with a
spinning black hole through O (G 3) to all orders in velocity, including linear and quadratic …

We describe a systematic framework for computing the conservative potential of a compact
binary system using modern tools from scattering amplitudes and effective field theory. Our …

It has been suggested that amplitudes for quantum higher-spin massive particles
exchanging gravitons lead, via a classical limit, to results for scattering of spinning black …

Making use of the recently derived, all-spin, opposite-helicity Compton amplitude, we
calculate the classical gravitational scattering amplitude for one spinning and one spinless …

Starting from the leading soft term of the 5-point amplitude, involving a graviton and two Kerr
black holes, that factorises into the product of the elastic amplitude without the graviton and …

Building on a recent paper in which we computed the canonical Hamiltonian of a spinning
test particle in curved spacetime, at linear order in the particle's spin, we work out an …

In this paper we study the two-body gravitational scattering of massive scalars with different
masses in general spacetime dimensions. We focus on the Regge limit (eikonal regime) of …

We use a previously developed scattering-amplitudes-based framework for determining two-
body Hamiltonians for generic binary systems with arbitrary spin S. By construction this …
