Motivated by conceptual problems in quantum theories of gravity, the gravitational eikonal
approach, inspired by its electromagnetic predecessor, has been successfully applied to the …

Using the N= 1 supersymmetric, spinning worldline quantum field theory formalism, we
compute the conservative spin-orbit part of the momentum impulse Δ pi μ, spin kick Δ S i μ …

A bstract Using a heavy-mass effective field theory (HEFT), we study gravitational-wave
emission in the scattering of two spinless black holes or neutron stars of arbitrary masses at …

We compute the radiation reacted momentum impulse Δ pi μ, spin kick Δ S i μ, and
scattering angle θ between two scattered spinning massive bodies (black holes or neutron …

We calculate the scattering amplitude of two rotating objects with the linear-in-curvature spin-
induced multipoles of Kerr black holes at O (G 2) and all orders in the spins of both objects …

A bstract We exhibit an initial-value formulation of the worldline quantum field theory (WQFT)
approach to the classical two-body problem in general relativity. We show that the …

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 …

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 …

A bstract We continue to investigate correspondences between, on the one hand, scattering
amplitudes for massive higher-spin particles and gravitons in appropriate quantum-to …

A bstract We calculate the inelastic 2→ 3 one-loop amplitude for the scattering of two point-
like, spinless objects with generic masses involving the additional emission of a single …
