Form Factor Alphabets and Antipodal Duality from Cluster Algebras
Song He, Jiahao Liu
We develop a cluster-algebraic description of symbol alphabets for chiral stress-tensor form factors in planar super-Yang--Mills theory. Motivated by unfolding the t…

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…
