Tree Amplitudes with Charged Matter in Pure Gauge Theory
Jacob L. Bourjaily, Michael Plesser, Philip Velie
We describe the implementation and usage of `fermionic_amplitudes.m', a Mathematica package for the computation of tree amplitudes involving arbitrary numbers of gauge bosons and a…

The Colour Dependence of Amplitudes
Jacob L. Bourjaily, Michael Plesser, Cristian Vergu
We describe how to construct a spanning set of linearly-independent, automatically orthogonal colour tensors for scattering amplitudes involving coloured particles transforming und…

The Many Colours of Amplitudes
Jacob L. Bourjaily, Michael Plesser, Cristian Vergu
We study the colour-dependence of scattering amplitudes in Yang-Mills theory with arbitrary (but fixed) gauge group and various representations of charged matter. When the rank of…
