Bootstrapping the Four-Point NMHV Stress-Tensor Form Factor
Song He, Jiahao Liu, Qinglin Yang
We bootstrap the four-point next-to-maximally helicity-violating (NMHV) form factor of the chiral stress-tensor supermultiplet in planar maximally supersymmetric Yang-Mills theory…
Notes on Diagrammatic Coaction for Cosmological Wavefunction Coefficients: A Two-Site Prelude
Yuhan Fu, Jiahao Liu
We study the coaction of cosmological wavefunction coefficients of conformally coupled scalars in FRW background of a two-site example, which turns out to have an elegant diagramma…
Heptagon Symbols at Five Loops and All-Loop Sequences
Song He, Xuhang Jiang, Xiang Li +1
We revisit the symbol bootstrap program for the seven-particle MHV and NMHV amplitudes in planar super-Yang-Mills (SYM) based on the alphabet associated with the $E…
Notes on conformal integrals: Coulomb branch amplitudes, magic identities and bootstrap
Song He, Xuhang Jiang, Jiahao Liu +1
We study multi-loop conformal integrals for four-point correlators of planar super-Yang-Mills theory, and in particular those contributing to Coulomb branch amplitudes…
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…
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…
On symbology and differential equations of Feynman integrals from Schubert analysis
Song He, Xuhang Jiang, Jiahao Liu +1
We take the first step in generalizing the so-called "Schubert analysis", originally proposed in twistor space for four-dimensional kinematics, to the study of symbol letters and m…
