A Symbol of Uniqueness: The Cluster Bootstrap for the 3-Loop MHV Heptagon
Seven-particle scattering amplitudes in planar super-Yang-Mills theory are believed to belong to a special class of generalised polylogarithm functions called heptagon functions. These are functions with physical branch cuts whose symbols may be written in terms of the 42 cluster A-coordinates on Gr...
