Cut-constructible part of QCD amplitudes
R Britto, B Feng, P Mastrolia - Physical Review D—Particles, Fields, Gravitation …, 2006 - APS
Unitarity cuts are widely used in analytic computation of loop amplitudes in gauge theories
such as QCD. We expand upon the technique introduced in hep-ph/0503132 to carry out …

On-shell recursion relations for all Born QCD amplitudes
C Schwinn, S Weinzierl - Journal of High Energy Physics, 2007 - iopscience.iop.org
We consider on-shell recursion relations for all Born QCD amplitudes. This includes
amplitudes with several pairs of quarks and massive quarks. We give a detailed description …

SUSY ward identities for multi-gluon helicity amplitudes with massive quarks
C Schwinn, S Weinzierl - Journal of High Energy Physics, 2006 - iopscience.iop.org
We use supersymmetric Ward identities to relate multi-gluon helicity amplitudes involving a
pair of massive quarks to amplitudes with massive scalars. This allows to use the recent …

Scattering amplitudes with massive fermions using BCFW recursion
KJ Ozeren, WJ Stirling - The European Physical Journal C-Particles and …, 2006 - Springer
We study the QCD scattering amplitudes for ̄qq→gg and ̄qq→ggg where q is a massive
fermion. Using a particular choice of massive fermion spinor we derive compact expressions …
