Bootstrapping octagons in reduced kinematics from cluster algebras
Song He, Zhenjie Li, Yichao Tang +1
Multi-loop scattering amplitudes/null polygonal Wilson loops in super-Yang-Mills are known to simplify significantly in reduced kinematics, where external legs/edg…
Notes on cluster algebras and some all-loop Feynman integrals
Song He, Zhenjie Li, Qinglin Yang
We study cluster algebras for some all-loop Feynman integrals, including box-ladder, penta-box-ladder, and (seven-point) double-penta-ladder integrals. In addition to the well-know…
Feynman Integrals and Scattering Amplitudes from Wilson Loops
Song He, Zhenjie Li, Qinglin Yang +1
We study Feynman integrals and scattering amplitudes in super-Yang-Mills by exploiting the duality with null polygonal Wilson loops. Certain Feynman integrals, includi…
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…
The symbol and alphabet of two-loop NMHV amplitudes from equations
Song He, Zhenjie Li, Chi Zhang
We study the symbol and the alphabet for two-loop NMHV amplitudes in planar super-Yang-Mills from the equations, which provide a first-principle method for c…
A Note on Letters of Yangian Invariants
Song He, Zhenjie Li
Motivated by reformulating Yangian invariants in planar SYM directly as forms on momentum-twistor space, we propose a purely algebraic problem of determining t…
