Loop Amplitudes in Pure Yang-Mills from Generalised Unitarity

Preprint English OPEN
Brandhuber, Andreas; McNamara, Simon; Spence, Bill; Travaglini, Gabriele;

We show how generalised unitarity cuts in D = 4 - 2 epsilon dimensions can be used to calculate efficiently complete one-loop scattering amplitudes in non-supersymmetric Yang-Mills theory. This approach naturally generates the rational terms in the amplitudes, as well a... View more
