One-loop derivation of the Wilson polygon–MHV amplitude duality
@article{Gorsky2009OneloopDO, title={One-loop derivation of the Wilson polygon–MHV amplitude duality}, author={A. S. Gorsky and Alexander Zhiboedov}, journal={Journal of Physics A: Mathematical and Theoretical}, year={2009}, volume={42}, pages={355214} }
We discuss the origin of the Wilson polygon–MHV amplitude duality at a perturbative level. It is shown that the duality for the MHV amplitudes at the one-loop level can be proven upon a particular change of variables in Feynman parametrization and with the use of the relation between Feynman integrals at different space-time dimensions. Some generalization of the duality which implies the insertion of a particular vertex operator at the Wilson triangle is found for the 3-point function. We…
