Stokes polytopes: the positive geometry for ϕ 4 interactions
Abstract In a remarkable recent work [1], the amplituhedron program was extended to the realm of non-supersymmetric scattering amplitudes. In particular it was shown that for tree-level planar diagrams in massless ϕ 3 theory (and its close cousin, bi-adjoint ϕ 3 theory) a polytope known as the assoc...
