All-loop cuts from the Amplituhedron

The definition of the amplituhedron in terms of sign flips involves both one-loop constraints and the "mutual positivityā€¯ 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...
