1. All-loop cuts from the Amplituhedron / Langer, Cameron ; Srikant, Akshay
The definition of the amplituhedron in terms of sign flips involves both one-loop constraints and the “mutual positivity” constraint. [...]

2. Deep Into the Amplituhedron: Amplitude Singularities at All Loops and Legs / Arkani-Hamed, Nima ; Langer, Cameron ; Srikant, Akshay Yelleshpur ; Trnka, Jaroslav
In this Letter we compute a canonical set of cuts of the integrand for maximally helicity violating amplitudes in planar N=4 supersymmetric Yang-Mills theory, where all internal propagators are put on shell. [...]
