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 purpose of this review is to bridge the gap between a standard course in quantum field
theory and recent fascinating developments in the studies of on-shell scattering amplitudes …

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 …

Providing a comprehensive, pedagogical introduction to scattering amplitudes in gauge
theory and gravity, this book is ideal for graduate students and researchers. It offers a …

A bstract Recently, a perturbative duality between gauge and gravity theories (the double
copy) has been discovered, that is believed to hold to all loop orders. In this paper, we …

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 …

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 show that the BRST Lagrangian double copy construction of supergravity as the
'square'of Yang–Mills theory finds a natural interpretation in terms of homotopy algebras. We …

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 Many gauge theories possess a hidden duality between color and kinematics in
their on-shell scattering amplitudes. An open problem is to formulate an off-shell realization …
