In this paper we provide a formula for the canonical differential form of thehypersimplex $\Delta_{k,n}$ for all $n$ and $k$. We also study thegeneralization of the momentum amplituhedron $\mathcal{M}_{n,k}$ to $m=2$, andwe conclude that the existing definition does not possess the desiredproperties. Nevertheless, we find interesting momentum amplituhedron-likelogarithmic differential forms in the $m=2$ version of the spinor helicityspace, that have the same singularity structure as the hypersimplex canonicalforms.

The hypersimplex canonical forms and the momentum amplituhedron-like logarithmic forms
