Landau-based Schubert analysis
Song He, Xuhang Jiang, Jiahao Liu +1
We revisit the conjectural method called Schubert analysis for generating the alphabet of symbol letters for Feynman integrals, which was based on geometries of intersecting lines…
From squared amplitudes to energy correlators
Song He, Xuhang Jiang, Qinglin Yang +1
The leading order -point energy correlators of maximally supersymmetric Yang-Mills theory in the limit where the detectors are collinear can be expressed as an integral of t…
Differential equations and recursive solutions for cosmological amplitudes
Song He, Xuhang Jiang, Jiahao Liu +2
Recently considerable efforts have been devoted to computing cosmological correlators and the corresponding wavefunction coefficients, as well as understanding their analytical str…
Symbol letters of Feynman integrals from Gram determinants
Xuhang Jiang, Jiahao Liu, Xiaofeng Xu +1
Symbol letters are crucial for analytically calculating Feynman integrals in terms of iterated integrals. We present a novel method to construct the symbol letters for a given inte…
