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 …

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 …

A bstract The duality between color and kinematics present in scattering amplitudes of Yang-
Mills theory strongly suggests the existence of a hidden kinematic Lie algebra that controls …

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 …

We propose a procedure to determine the moduli-space integrands of loop-level superstring
amplitudes for massless external states in terms of the field theory limit. We focus on the type …

A bstract We derive from ambitwistor strings new formulae for two-loop scattering amplitudes
in supergravity and super-Yang-Mills theory, with any number of particles. We start by …

A bstract We present new and explicit formulae for the one-loop integrands of scattering
amplitudes in non-supersymmetric gauge theory and gravity, valid for any number of …

A bstract We reformulate the monodromy relations of open-string scattering amplitudes as
boundary terms of twisted homologies on the configuration spaces of Riemann surfaces of …

A bstract We present new formulas for one-loop ambitwistor-string correlators for gauge
theories in any even dimension with arbitrary combinations of gauge bosons, fermions and …

A bstract Color-kinematics duality is a remarkable conjectured property of gauge theory
which, together with double copy, is at the heart of a wealth of new developments in …
