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 …

We give a comprehensive review of recent developments on using the pure spinor
formalism to compute massless superstring scattering amplitudes at tree level. The main …

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 …

The double copy is, in essence, a map between scattering amplitudes in a broad variety of
familiar field and string theories. In addition to the mathematically rich intrinsic structure, it …

We show that self-dual gravity in Euclidean four-dimensional anti–de Sitter space (AdS 4)
can be described by a scalar field with a cubic interaction written in terms of a deformed …

We present a closed formula for all Bern-Carrasco-Johansson (BCJ) numerators describing
D-dimensional tree-level scattering amplitudes in a heavy-mass effective field theory with …

A bstract We explain how the lowest-order classical gravitational radiation produced during
the inelastic scattering of two Schwarzschild black holes in General Relativity can be …

We use the recently developed generalized double-copy construction to obtain an improved
representation of the five-loop four-point integrand of N= 8 supergravity whose leading …

A bstract We explore color-kinematic duality for tree-level AdS/CFT correlators in momentum
space. We start by studying the bi-adjoint scalar in AdS at tree-level as an illustrative …

We perturbatively calculate classical radiation in Yang-Mills theory and dilaton gravity, to
next-to-leading order in couplings. The radiation is sourced by the scattering of two …
