QCD corrections to the hadronic production of a heavy quark pair and a W-boson including decay correlations
Simon Badger, John M. Campbell, R. K. Ellis
We perform an analytic calculation of the one-loop amplitude for the W-boson mediated process 0 \to d u-bar Q Q-bar l-bar l, retaining the mass for the quark Q. The momentum of eac…
NGluon: A Package to Calculate One-loop Multi-gluon Amplitudes
Simon Badger, Benedikt Biedermann, Peter Uwer
We present a computer library for the numerical evaluation of colour-ordered n-gluon amplitudes at one-loop order in pure Yang-Mills theory. The library uses the recently developed…
Analytic Computations of Massive One-Loop Amplitudes
Simon Badger, Ralf Sattler, Valery Yundin
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 contrib…
Compact QED Tree-Level Amplitudes From Dressed BCFW Recursion Relations
Simon Badger, Johannes M. Henn
We construct a modified on-shell BCFW recursion relation to derive compact analytic representations of tree-level amplitudes in QED. As an application, we study the amplitudes of a…
