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…
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…
Cuts and Isogenies
Hjalte Frellesvig, Cristian Vergu, Matthias Volk +1
We consider the genus-one curves which arise in the cuts of the sunrise and in the elliptic double-box Feynman integrals. We compute and compare invariants of these curves in a num…
