Landau singularities from the amplituhedron

Abstract We propose a simple geometric algorithm for determining the complete set of branch points of amplitudes in planar N $$ \mathcal{N} $$ = 4 super-Yang-Mills theory directly from the amplituhedron, without resorting to any particular representation in terms of local Feynman integrals. This rep...
