The infrared structure of perturbative gauge theories
Infrared divergences in the perturbative expansion of gauge theory amplitudes and cross
sections have been a focus of theoretical investigations for almost a century. New insights …

Scattering amplitudes
H Elvang, Y Huang - ar** the three-loop hexagon
A bstract We consider the hexagonal Wilson loop dual to the six-point MHV amplitude in
planar\(\mathcal {N}= 4\) super Yang-Mills theory. We apply constraints from the operator …

Simplifying multiloop integrands and ultraviolet divergences of gauge theory<? format?> and gravity amplitudes
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 …
