The Duality Between Color and Kinematics and its Applications
/ Bern, Zvi (UCLA ; CERN) ; Carrasco, John Joseph (Northwestern U. ; IPhT, Saclay) ; Chiodaroli, Marco (Uppsala U.) ; Johansson, Henrik (Uppsala U. ; Stockholm U. ; Royal Inst. Tech., Stockholm) ; Roiban, Radu (Pennsylvania U.)
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 theories. We emphasize, in particular, applications to loop-level calculations, the broad web of theories linked by the duality and the associated double-copy structure, and the issue of extending the duality and double copy beyond scattering amplitudes.

Black Hole Binary Dynamics from the Double Copy and Effective Theory
/ Bern, Zvi (UCLA ; CERN) ; Cheung, Clifford (Caltech, Pasadena (main)) ; Roiban, Radu (Penn State U., University Park, IGC) ; Shen, Chia-Hsien (UCLA) ; Solon, Mikhail P. (Caltech, Pasadena (main)) ; Zeng, Mao (Zurich, ETH)
We describe a systematic framework for computing the conservative potential of a compact binary system using modern tools from scattering amplitudes and effective field theory. Our approach combines methods for integration and matching adapted from effective field theory, generalized unitarity, and the double-copy construction, which relates gravity integrands to simpler gauge-theory expressions. [...]

The generalized double copy and its applications to UV properties of supergravity theories.
/ Bern, Zvi (speaker)
Recent years have seen enormous progress in our ability to compute elementary-particle scattering processes in quantum field theory. We will describe the application of modern ideas, including the duality between color and kinematics and advanced loop-integration methods, to studies of the ultraviolet properties of quantum gravity theories.

Double-Copy Constructions and Unitarity Cuts
/ Bern, Zvi (CERN ; UCLA) ; Davies, Scott (UCLA) ; Nohle, Josh (Nordita ; Royal Inst. Tech., Stockholm ; Stockholm U.)
The duality between color and kinematics enables the construction of multiloop gravity integrands directly from corresponding gauge-theory integrands. This has led to new nontrivial insights into the structure of gravity theories, including the discovery of enhanced ultraviolet cancellations. [...]

Evanescent Effects Can Alter Ultraviolet Divergences in Quantum Gravity without Physical Consequences
/ Bern, Zvi (UCLA ; CERN) ; Cheung, Clifford (Caltech, Pasadena (main)) ; Chi, Huan-Hang (SLAC) ; Davies, Scott (UCLA) ; Dixon, Lance (Caltech, Pasadena (main) ; SLAC) ; Nohle, Josh (UCLA)
Evanescent operators such as the Gauss-Bonnet term have vanishing perturbative matrix elements in exactly D=4 dimensions. Similarly, evanescent fields do not propagate in D=4; a three-form field is in this class, since it is dual to a cosmological-constant contribution. [...]

D = 5 maximally supersymmetric Yang-Mills theory diverges at six loops
/ Bern, Zvi (UCLA) ; Carrasco, John Joseph (Stanford U., ITP ; Stanford U., Phys. Dept.) ; Dixon, Lance J. (SLAC) ; Douglas, Michael R. (SUNY, Stony Brook ; IHES, Bures-sur-Yvette) ; von Hippel, Matt (SUNY, Stony Brook) ; Johansson, Henrik (CERN ; Saclay)
The connection of maximally supersymmetric Yang-Mills theory to the (2,0) theory in six dimensions has raised the possibility that it might be perturbatively ultraviolet finite in five dimensions. We test this hypothesis by computing the coefficient of the first potential ultraviolet divergence of planar (large $N_c$) maximally supersymmetric Yang-Mills theory in D = 5, which occurs at six loops.
