BCFW recursion for light-like Wilson loop correlators
James Drummond, Matthew Rochford, Rowan Wright
We apply the idea of holomorphic linking (arXiv:1101.1329) to correlators of multiple light-like loop operators in super Yang-Mills theory. This allows us to extend…
Tropical symmetries of cluster algebras
James Drummond, Ãmer GürdoÄan, Jian-Rong Li
We study tropicalisations of quasi-automorphisms of cluster algebras and show that their induced action on the g-vectors can be realized by tropicalising their action on the homoge…
Leading singularities of Wilson loop correlators from twistor Wilson loop diagrams
James Drummond, Matthew Rochford, Rowan Wright
The leading singularities of one-loop scattering amplitudes in planar super Yang-Mills theory are known to factorise into products of tree-level amplitudes, and thi…
Light-like Wilson loops and the -equation
James Drummond, Matthew Rochford, Rowan Wright
In recent work we began a study of the correlators of multiple light-like Wilson loops in super Yang-Mills theory, focussing primarily on tree-level calculations an…
Light-like Wilson loop correlators
James Drummond, Ãmer GürdoÄan, Matthew Rochford +1
It is well-known that the expectation values of null polygonal Wilson loops computed in planar \(\mathcal{N}=4\) super Yang-Mills theory are dual to MHV amplitudes in that theory,…
Singularities of massless scattering and cluster algebras
Lara Bossinger, James Drummond, Ross Glew +2
Partial flag varieties arise in the context of massless scattering kinematics. They can be associated to both spinor-helicity variables and momentum twistor variables in two separa…
