Two-loop $\mathcal{N}$ = 2 SQCD amplitudes with external matter from iterated cuts
- Abstract:
-
We develop an iterative method for constructing four-dimensional generalized unitarity cuts in $\mathcal{N}$ = 2 supersymmetric Yang-Mills (SYM) theory coupled to fundamental matter hypermultiplets ($\mathcal{N}$ = 2 SQCD). For iterated two-particle cuts, specifically those involving only four-point amplitudes, this implies simple diagrammatic rules for assembling the cuts to any loop order, reminiscent of the rung rule in $\mathcal{N}$ = 4 SYM. By identifying physical poles, the construction...
