Folding Amplitudes into Form Factors: An Antipodal Duality
Lance J. Dixon, Omer Gurdogan, Andrew J. McLeod +1
We observe that the three-gluon form factor of the chiral part of the stress-tensor multiplet in planar super-Yang-Mills theory is dual to the six-gluon MHV amplitu…
Implications of the Landau Equations for Iterated Integrals
Holmfridur S. Hannesdottir, Andrew J. McLeod, Matthew D. Schwartz +1
We introduce a method for deriving constraints on the symbol of Feynman integrals from the form of their asymptotic expansions in the neighborhood of Landau loci. In particular, we…
The Two-Loop Remainder Function for Eight and Nine Particles
John Golden, Andrew J. McLeod
Two-loop MHV amplitudes in planar supersymmetric Yang Mills theory are known to exhibit many intriguing forms of cluster-algebraic structure. We leverage this struct…
Direct Integration for Multi-leg Amplitudes: Tips, Tricks, and When They Fail
Jacob L. Bourjaily, Yang-Hui He, Andrew J. McLeod +5
Direct hyperlogarithmic integration offers a strong alternative to differential equation methods for Feynman integration, particularly for multi-particle diagrams. We review a vari…
