Analytic Computations of Massive One-Loop Amplitudes
arXiv:1006.5011 · doi:10.1016/j.nuclphysbps.2010.08.020
Abstract
We show some new applications of on-shell methods to calculate compact helicity amplitudes for t tbar production through gluon fusion. The rational and mass renormalisation contributions are extracted from two independent Feynman diagram based approaches.
