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…

The Landau Bootstrap
Holmfridur Hannesdottir, Andrew McLeod, Matthew D. Schwartz +1
We advocate a strategy of bootstrapping Feynman integrals from just knowledge of their singular behavior. This approach is complementary to other bootstrap programs, which exploit…
