We use the recently developed generalized double-copy procedure to construct an integrand for the fiveloop four-point amplitude of N = 8 supergravity. This construction starts from a naive double c ... 
All-Multiplicity Nonplanar Amplitude Integrands in Maximally Supersymmetric Yang-Mills Theory at Two Loops.
We give a prescriptive representation of all-multiplicity two-loop maximally-helicity-violating (MHV) amplitude integrands in fully-color-dressed (nonplanar) maximally supersymmetric Yang-MillsExpand
Local BCJ numerators for ten-dimensional SYM at one loop
Abstract We obtain local numerators satisfying the BCJ color-kinematics duality at one loop for super-Yang-Mills theory in ten dimensions. This is done explicitly for six points via the field-theoryExpand
Double-Copy Structure of One-Loop Open-String Amplitudes.
TLDR
Evidence is provided for a new double-copy structure in one-loop amplitudes of the open superstring where gauge-invariant kinematic factors and certain functions of the punctures-so-called generalized elliptic integrands-enter on completely symmetric footing. Expand
Ultraviolet properties of N=8 supergravity at five loops
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 ultravioletExpand
Superstring Loop Amplitudes from the Field Theory Limit
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 IIExpand
S-duality and the double copy
The double copy formalism provides an intriguing connection between gauge theories and gravity. It was first demonstrated in the perturbative context of scattering amplitudes but recently theExpand
Two-loop N = 2 SQCD amplitudes with external matter from iterated cuts
We develop an iterative method for constructing four-dimensional generalized unitarity cuts in N=2 supersymmetric Yang-Mills (SYM) theory coupled to fundamental matter hypermultiplets (N=2 SQCD). ForExpand
Comments on the double copy construction for gravitational theories
We revisit the double copy description for linearized gravity and point out various technical issues and subtleties, associated with setting up the double copy description, including the problem ofExpand
BRST-Lagrangian Double Copy of Yang-Mills Theory.
We show that the double copy of gauge theory amplitudes to $\mathcal{N}=0$ supergravity amplitudes extends from tree level to loop level. We first explain that color-kinematic duality is a conditionExpand
Double copy of massive scalar QCD
We construct the gravitational theory emerging from the double-copy of massive scalar quantum chromodynamics in general dimensions. The resulting two-form-dilaton-gravity theory couples to flavoredExpand
