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. [...]

Simplifying Multiloop Integrands and Ultraviolet Divergences of Gauge Theory and Gravity Amplitudes / Bern, Z (UCLA ; UC, Santa Barbara ; CERN) ; Carrasco, J J M (Stanford U., Phys. Dept. ; Stanford U., ITP ; UC, Santa Barbara) ; Dixon, L J (SLAC ; CERN) ; Johansson, H (Saclay, SPhT ; UC, Santa Barbara) ; Roiban, R (Penn State U. ; UC, Santa Barbara)
We use the duality between color and kinematics to simplify the construction of the complete four-loop four-point amplitude of N=4 super-Yang-Mills theory, including the nonplanar contributions. The duality completely determines the amplitude's integrand in terms of just two planar graphs. [...]

Spontaneously Broken Yang-Mills-Einstein Supergravities as Double Copies / Chiodaroli, Marco (Potsdam, Max Planck Inst.) ; Gunaydin, Murat (Penn State U., University Park, IGC) ; Johansson, Henrik (Uppsala U. ; CERN ; Nordita) ; Roiban, Radu (Penn State U., University Park, IGC ; Santa Barbara, KITP)
Color/kinematics duality and the double-copy construction have proved to be systematic tools for gaining new insight into gravitational theories. Extending our earlier work, in this paper we introduce new double-copy constructions for large classes of spontaneously-broken Yang-Mills-Einstein theories with adjoint Higgs fields. [...]

Color-Kinematics Duality in Multi-Regge Kinematics and Dimensional Reduction / Johansson, Henrik (CERN) ; Sabio Vera, Agustín (Madrid, Autonoma U.) ; Serna Campillo, Eduardo (Salamanca U., IUFFyM) ; Vázquez-Mozo, Miguel Á. (Salamanca U., IUFFyM)
In this note we study the applicability of the color-kinematics duality to the scattering of two distinguishable scalar matter particles with gluon emission in QCD, or graviton emission in Einstein gravity. Previous analysis suggested that direct use of the Bern-Carrasco-Johansson double-copy prescription to matter amplitudes does not reproduce the gravitational amplitude in multi-Regge kinematics.

Scattering amplitudes in N=2 Maxwell-Einstein and Yang-Mills/Einstein supergravity / Chiodaroli, Marco (Potsdam, Max Planck Inst.) ; Günaydin, Murat (Penn State U., University Park, IGC ; Penn State U.) ; Johansson, Henrik (CERN) ; Roiban, Radu (Penn State U., University Park, IGC ; Penn State U.)
We expose a double-copy structure in the scattering amplitudes of the generic Jordan family of N=2 Maxwell-Einstein and Yang-Mills/Einstein supergravity theories in four and five dimensions. The Maxwell-Einstein supergravity amplitudes are obtained through the color/kinematics duality as a product of two gauge-theory factors; one originating from pure N=2 super-Yang-Mills theory and the other from the dimensional reduction of a bosonic higher-dimensional pure Yang-Mills theory. [...]

Bootstrapping the UV from the IR via Double Copy Consistency / Pavao, Nic (speaker) (Northwestern University)
Traditionally the double copy is praised for efficient construction of gravitational S-matrix elements at high orders in perturbation theory, by way of simpler gauge theory building blocks. In this talk, we will find that color-kinematics duality can also be used to inform UV completion of effective field theories (EFTs). [...]

Equivalent D=3 Supergravity Amplitudes from Double Copies of Three-Algebra and Two-Algebra Gauge Theories / Huang, Yu-tin (Michigan U., MCTP ; Michigan U. ; UCLA) ; Johansson, Henrik (CERN ; Saclay, SPhT)
We show that three-dimensional supergravity amplitudes can be obtained as double copies of either three-algebra super-Chern-Simons matter theory or that of two-algebra super-Yang-Mills theory, when either theory is organized to display the color-kinematics duality. We prove that only helicity-conserving four-dimensional gravity amplitudes have nonvanishing descendants when reduced to three dimensions; implying the vanishing of odd-multiplicity S-matrix elements, in agreement with Chern-Simons matter theory. [...]

Pure Gravities via Color-Kinematics Duality for Fundamental Matter / Johansson, Henrik (CERN) ; Ochirov, Alexander (IPhT, Saclay)
We give a prescription for the computation of loop-level scattering amplitudes in pure Einstein gravity, and four-dimensional pure supergravities, using the color-kinematics duality. Amplitudes are constructed using double copies of pure (super-)Yang-Mills parts and additional contributions from double copies of fundamental matter, which are treated as ghosts. [...]

The seeds of EFT double copy / Bonnefoy, Quentin (DESY) ; Durieux, Gauthier (CERN) ; Grojean, Christophe (DESY ; Humboldt U., Berlin) ; Machado, Camila S. (DESY) ; Roosmale Nepveu, Jasper (Humboldt U., Berlin)
We explore the double copy of effective field theories (EFTs), in the recently proposed generalized color-kinematics and Kawai-Lewellen-Tye (KLT) approaches. In the former, we systematically construct scalar numerators satisfying the Jacobi identities from simpler numerator "seeds" with trace-like permutation properties. [...]
