Scattering amplitudes and Wilson loops in twistor space (2011)
Journal Article
Adamo, T., Bullimore, M., Mason, L., & Skinner, D. (2011). Scattering amplitudes and Wilson loops in twistor space. Journal of Physics A: Mathematical and Theoretical, 44(45), Article 454008. https://doi.org/10.1088/1751-8113/44/45/454008

This paper reviews the recent progress in twistor approaches to Wilson loops, amplitudes and their duality for $\mathcal {N}=4$ super-Yang–Mills. Wilson loops and amplitudes are derived from first principles using the twistor action for maximally sup... Read More about Scattering amplitudes and Wilson loops in twistor space.

MHV diagrams from an all-loop recursion relation (2011)
Journal Article
Bullimore, M. (2011). MHV diagrams from an all-loop recursion relation. Journal of High Energy Physics, 2011(08), Article 107. https://doi.org/10.1007/jhep08%282011%29107

We derive an all-loop recursion relation for the rational integrands of scattering amplitudes in planar N=4 super Yang-Mills theory. The recursion relation is generated by an all-line shift of momentum twistors. We solve the recursion relation in det... Read More about MHV diagrams from an all-loop recursion relation.

A proof of the correlation function/supersymmetric Wilson loop correspondence (2011)
Journal Article
Adamo, T., Bullimore, M., Mason, L., & Skinner, D. (2011). A proof of the correlation function/supersymmetric Wilson loop correspondence. Journal of High Energy Physics, 2011(08), Article 076. https://doi.org/10.1007/jhep08%282011%29076

We prove that in the limit when its insertion points become pairwise null-separated, the ratio of certain n-point correlation functions in N=4 SYM is equal to a supersymmetric Wilson loop on twistor space, acting in the adjoint representation. In the... Read More about A proof of the correlation function/supersymmetric Wilson loop correspondence.

Inverse soft factors and grassmannian residues (2011)
Journal Article
Bullimore, M. (2011). Inverse soft factors and grassmannian residues. Journal of High Energy Physics, 2011(01), Article 055. https://doi.org/10.1007/jhep01%282011%29055

The action of holomorphic inverse soft factors on scattering amplitudes in N=4 SYM is shown to take a remarkably simple form in momentum twistor space. This is used to identify individual residues of the grassmannian with primitive leading singularit... Read More about Inverse soft factors and grassmannian residues.
