Functions Beyond Multiple Polylogarithms for Precision Collider Physics
Jacob L. Bourjaily, Johannes Broedel, Ekta Chaubey +14
Feynman diagrams constitute one of the essential ingredients for making precision predictions for collider experiments. Yet, while the simplest Feynman diagrams can be evaluated in…
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…
Steinmann Relations and the Wavefunction of the Universe
Paolo Benincasa, Andrew J. McLeod, Cristian Vergu
The physical principles of causality and unitarity put strong constraints on the analytic structure of the flat-space S-matrix. In particular, these principles give rise to the Ste…
Sequential Discontinuities of Feynman Integrals and the Monodromy Group
Jacob L. Bourjaily, Holmfridur Hannesdottir, Andrew J. McLeod +2
We generalize the relation between discontinuities of scattering amplitudes and cut diagrams to cover sequential discontinuities (discontinuities of discontinuities) in arbitrary m…
The Steinmann Cluster Bootstrap for N=4 Super Yang-Mills Amplitudes
Simon Caron-Huot, Lance J. Dixon, James M. Drummond +6
We review the bootstrap method for constructing six- and seven-particle amplitudes in planar super Yang-Mills theory, by exploiting their analytic structure. We foc…
