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…

On Solving Dual Conformal Integrals in Coulomb-branch Amplitudes and Their Periods
Song He, Xuhang Jiang
We define and study infinite families of all-loop planar, dual conformal invariant (DCI) integrals, which contribute to four-point Coulomb-branch amplitudes and correlators in ${\c…

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…
