Boundaries of Amplituhedra and NMHV Symbol Alphabets at Two Loops
Igor Prlina, Marcus Spradlin, James Stankowicz +1
In this sequel to arXiv:1711.11507 we classify the boundaries of amplituhedra relevant for determining the branch points of general two-loop amplitudes in planar su…

All-Helicity Symbol Alphabets from Unwound Amplituhedra
Igor Prlina, Marcus Spradlin, James Stankowicz +2
We review an algorithm for determining the branch points of general amplitudes in planar super-Yang-Mills theory from amplituhedra. We demonstrate how to use the re…

Evidence for a Nonplanar Amplituhedron
Zvi Bern, Enrico Herrmann, Sean Litsey +2
The scattering amplitudes of planar N = 4 super-Yang-Mills exhibit a number of remarkable analytic structures, including dual conformal symmetry and logarithmic singularities of in…
