Augmented Recursion For One-loop Amplitudes
arXiv:1011.0559 · doi:10.1016/j.nuclphysbps.2010.08.022
Abstract
We present a semi-recursive method for calculating the rational parts of one-loop amplitudes when recursion produces double poles. We illustrate this with the graviton scattering amplitude M^{1-loop}(1-, 2+, 3+, 4+, 5+).
