This review describes the duality between color and kinematics and its applications, with the
aim of gaining a deeper understanding of the perturbative structure of gauge and gravity …

The study of general two-dimensional models of gravity allows to tackle basic questions of
quantum gravity, bypassing important technical complications which make the treatment in …

A bstract We compute classical gravitational observables for the scattering of two spinless
black holes in general relativity and\(\mathcal {N}\)= 8 supergravity in the formalism of …

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 …

We present the amplitude for classical scattering of gravitationally interacting massive
scalars at third post-Minkowskian order. Our approach harnesses powerful tools from the …

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 …

We analyze constraints from perturbative unitarity and crossing on the leading contributions
of higher-dimension operators to the four-graviton amplitude in four spacetime dimensions …

A bstract The classical scattering of spinning objects is well described by the spinor-helicity
formalism for heavy particles. Using these variables, we derive spurious-pole-free, all-spin …

Advances in scattering amplitudes have exposed previously-hidden color-kinematics and
double-copy structures in theories ranging from gauge and gravity theories to effective field …

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 …
