Analytic Computations of Massive One-Loop Amplitudes

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.
