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 study of higher-dimensional black holes is a subject which has recently attracted vast
interest. Perhaps one of the most surprising discoveries is a realization that the properties of …

A bstract A precise link is derived between scalar-graviton S-matrix elements and
expectation values of operators in a worldline quantum field theory (WQFT), both used to …

We show how to compute classical wave observables using quantum scattering amplitudes.
We discuss observables both with incoming and with outgoing waves. The required …

We review recent progress and future prospects for harnessing powerful tools from
theoretical high-energy physics, such as scattering amplitudes and effective field theory, to …

We develop a general formalism for computing classical observables for relativistic
scattering of spinning particles, directly from on-shell amplitudes. We then apply this …

Scattering amplitudes have their origin in quantum field theory, but have wide-ranging
applications extending to classical physics. We review a formalism to connect certain …

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 …

We argue that the complex transformation relating the Schwarzschild to the Taub-NUT
metric, introduced by Talbot, is in fact an electric-magnetic duality transformation. We show …

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 …
