Unitarity Cuts with Massive Propagators and Algebraic Expressions for Coefficients
Ruth Britto, Bo Feng
In the first part of this paper, we extend the d-dimensional unitarity cut method of hep-ph/0609191 to cases with massive propagators. We present formulas for integral reduction wi…

D-dimensional unitarity cut method
Charalampos Anastasiou, Ruth Britto, Bo Feng +2
We develop a unitarity method to compute one-loop amplitudes with massless propagators in d=4-2*epsilon dimensions. We compute double cuts of the loop amplitudes via a decompositio…
