Leading Singularities of the Two-Loop Six-Particle MHV Amplitude
Freddy Cachazo, Marcus Spradlin, Anastasia Volovich
We use the leading singularity technique to determine the planar six-particle two-loop MHV amplitude in N=4 super Yang-Mills in terms of a simple basis of integrals. Our result for…

Sharpening The Leading Singularity
Freddy Cachazo
We show how studying leading singularities of Feynman diagrams, when all momenta are complex, gives a simple way of writing multi-loop and multi-particle scattering amplitudes in N…

On the structure of scattering amplitudes in N=4 super Yang-Mills and N=8 supergravity
Freddy Cachazo, David Skinner
Exploiting singularities in Feynman integrals to get information about scattering amplitudes has been particularly useful at one-loop in theories where no triangles or bubbles appe…
