Multivariate Residues and Maximal Unitarity
Mads Sogaard, Yang Zhang
We extend the maximal unitarity method to amplitude contributions whose cuts define multidimensional algebraic varieties. The technique is valid to all orders and is explicitly dem…

Global Residues and Two-Loop Hepta-Cuts
Mads Sogaard
We examine maximal unitarity in the nonplanar case and derive remarkably compact analytic expressions for coefficients of master integrals with two-loop crossed box topology in mas…
