Description
In the calculation of loop-level amplitudes the use of 4-dimensional unitarity cuts over D-dimensional cuts offers simplifications, both theoretical and computational, but at the cost of being unable to detect certain rational terms. We can reconstruct these rational terms using BCFW recursion, however the presence of double poles at two-loop level requires us to modify the traditional technique. In this talk we will look at a work in progress, using Augmented Recursion to calculate the rational part of the two-loop five-point single-minus Yang-Mills amplitude, with a view to extend the method to higher point amplitudes.
