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 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 …

A bstract The search for a theory of the S-Matrix over the past five decades has revealed
surprising geometric structures underlying scattering amplitudes ranging from the string …

We briefly review the manifold incarnations and facets of the notion that gravity, in certain
regards, can be re-conceived as the product of two gauge theories. We begin with a short …

A bstract We systematically explore the space of scalar effective field theories (EFTs)
consistent with a Lorentz invariant and local S-matrix. To do so we define an EFT …

A bstract Recent works have explored how scattering amplitudes in quantum self-dual Yang-
Mills theory and self-dual gravity can be interpreted as resulting from an anomaly, as first …

A bstract We take a major step towards computing D-dimensional one-loop amplitudes in
general gauge theories, compatible with the principles of unitarity and the color-kinematics …

Biadjoint scalar theories are novel field theories that arise in the study of non-abelian gauge
and gravity amplitudes. In this short paper, we present exact nonperturbative solutions of the …

A bstract Scattering amplitudes in Yang-Mills theory are known to exhibit kinematic
structures which hint to an underlying kinematic algebra that is dual to the gauge group color …

A bstract Previous work has shown that massless tree amplitudes of the type I and IIA/B
superstrings can be dramatically simplified by expressing them as double copies between …
