Internal boundaries of the loop amplituhedron by Dian, Gabriele, Heslop, Paul, Stewart, Alastair

“…The strict definition of positive geometry implies that all maximal residues of its canonical form are ±1 ± 1 . We observe, however, that the loop integrand of…”

The two-loop Amplituhedron by Dian, Gabriele, Mazzucchelli, Elia, Tellander, Felix

“…The loop-Amplituhedron $\mathcal{A}^{(L)}_{n}$ is a semialgebraic set in the product of Grassmannians $\mathrm{Gr}_{\mathbb{R}}(2,4)^L$. Recently, many aspects…”
