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 …

A bstract We compute the next-to-leading order term in the scattering waveform of
uncharged black holes in classical general relativity and of half-BPS black holes in\(\mathcal …

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 …

The double copy is a much-studied relationship between gauge theory and gravity
amplitudes. Recently, this was generalised to an infinite family of classical solutions to …

A bstract The double copy relates scattering amplitudes in gauge and gravity theories. In this
paper, we expand the scope of the double copy to construct spacetime metrics through a …

A bstract Advances in our understanding of perturbation theory suggest the existence of a
correspondence between classical general relativity and Yang-Mills theory. A concrete …

A bstract The Weyl double copy is a procedure for relating exact solutions in biadjoint scalar,
gauge and gravity theories, and relates fields in spacetime directly. Where this procedure …

A bstract The double copy formalism provides an intriguing connection between gauge
theories and gravity. It was first demonstrated in the perturbative context of scattering …

A bstract The double copy is a map from non-abelian gauge theories to gravity, that has
been demonstrated both for scattering amplitudes and exact classical solutions. In this study …
