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 …

We show that double-copy maps for amplitudes in effective field theory are severely
constrained at four points by self-consistency and locality at six points. The resulting double …

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 …

We study the double-copy relation between classical solutions in gauge theory and gravity,
focusing on four-dimensional vacuum metrics of algebraic type D, a class that includes …

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 formulate a new program to generalize the double-copy of tree amplitudes. The
approach exploits the link between the identity element of the “KLT algebra” and the KLT …

A bstract We describe on-shell methods for computing one-and two-loop anomalous
dimensions in the context of effective field theories containing higher-dimension operators …

We demonstrate a physical motivation for extending color-dual or Bern-Carrasco-Johansson
(BCJ) double-copy construction to include theories with kinematic numerators that obey the …

Invoking increasingly higher dimension operators to encode novel UV physics in effective
gauge and gravity theories traditionally means working with increasingly more finicky and …
