Eight loop form factors, amplitudes and patterns in planar super-Yang-Mills theory
Lance J. Dixon, Zhenjie Li
The simplest nontrivial amplitude in planar super-Yang-Mills theory is six-gluon scattering in the maximally-helicity-violating configuration. It has been computed…
Kinematics, cluster algebras and Feynman integrals
Song He, Zhenjie Li, Qinglin Yang
We identify cluster algebras for planar kinematics of conformal Feynman integrals in four dimensions, as sub-algebras of that for top-dimensional corresponding to -poin…
Two-loop MHV Form Factors from the Periodic Wilson Loop
Zhenjie Li
We discuss how to compute maximal-helicity-violating (MHV) form factors for the chiral part of the stress-tensor supermultiplet from periodic light-like polygon Wilson loops in pla…
Integrating the full four-loop negative geometries and all-loop ladder-type negative geometries in ABJM theory
Zhenjie Li
The decomposition of the four-point ABJM amplituhedron into negative geometries produces compact integrands of logarithmic of amplitudes such that the infrared divergence only come…
