Singularities of eight- and nine-particle amplitudes from cluster algebras and tropical geometry
Abstract We further exploit the relation between tropical Grassmannians and Gr(4, n) cluster algebras in order to make and refine predictions for the singularities of scattering amplitudes in planar N $$ \mathcal{N} $$ = 4 super Yang-Mills theory at higher multiplicity n ≥ 8. As a mathematical found...
