Jumpstarting (elliptic) symbol integrations for loop integrals
Song He, Yichao Tang
We derive an algorithm for computing the total differentials of multi-loop integrals expressed as one-fold integrals of multiple polylogarithms, which can involve square roots of p…
Cutting the traintracks: Cauchy, Schubert and Calabi-Yau
Qu Cao, Song He, Yichao Tang
In this note we revisit the maximal-codimension residues, or leading singularities, of four-dimensional -loop traintrack integrals with massive legs, both in Feynman parameter s…
The symbology of Feynman integrals from twistor geometries
Song He, Jiahao Liu, Yichao Tang +1
We study the symbology of planar Feynman integrals in dimensional regularization by considering geometric configurations in momentum twistor space corresponding to their leading si…
The Wilson-loop representation for Feynman integrals
Song He, Zhenjie Li, Yichao Tang +1
We introduce and study the Wilson-loop representation of certain Feynman integrals for scattering amplitudes in SYM and beyond, which makes their evaluat…
