### All-loop cuts from the Amplituhedron

The definition of the amplituhedron in terms of sign flips involves both one-loop constraints and the "mutual positivity” constraint. To gain an understanding of the all-loop integrand of N=4$$\mathcal{N}=4$$ sYM requires understanding the crucial role played by mutual positivity. This paper...
