On-Shell Unitarity Bootstrap for QCD Amplitudes
arXiv:hep-ph/0610089 · doi:10.1016/j.nuclphysbps.2006.09.114
Abstract
We describe the recently developed on-shell bootstrap for computing one-loop amplitudes in non-supersymmetric theories such as QCD. The method combines the unitarity method with loop-level on-shell recursion. The unitarity method is used to compute cut-containing parts of amplitudes, and on-shell recursion is used for the remaining rational terms.
