We provide evidence that the classical scattering of two spinning black holes is controlled by
the soft expansion of exchanged gravitons. We show how an exponentiation of Cachazo …

A bstract Quantum scattering amplitudes for massive matter have received new attention in
connection to classical calculations relevant to gravitational-wave physics. Amplitude …

We study the link between classical scattering of spinning black holes and quantum
amplitudes for massive spin-s particles. Generic spin orientations of the black holes are …

The duality between color and kinematics was originally observed for purely adjoint
massless gauge theories, and later found to hold even after introducing massive fermionic …

A bstract The quantum field-theoretic approach to classical observables due to Kosower,
Maybee and O'Connell provides a rigorous pathway from on-shell scattering amplitudes to …

Advanced methods for computing perturbative, quantum-gravitational scattering amplitudes
show great promise for improving our knowledge of classical gravitational dynamics. This is …

A bstract It has been shown that a special set of three-point amplitudes between two
massive spinning states and a graviton reproduces the linearised stress-energy tensor for a …

We propose a new, chiral description for massive higher-spin particles in four spacetime
dimensions, which facilitates the introduction of consistent interactions. As proof of concept …

Recently, the gravitational scattering of two black holes (BHs) treated at the leading order in
the weak-field, or post-Minkowskian (PM), approximation to general relativity has been …

A bstract We apply on-shell methods to the bottom-up construction of electroweak
amplitudes, allowing for both renormalizable and non-renormalizable interactions. We use …
