Evidence for a nonplanar amplituhedron
/ Bern, Zvi ; Herrmann, Enrico ; Litsey, Sean ; Stankowicz, James ; et al

Logarithmic singularities and maximally supersymmetric amplitudes
/ Bern, Zvi ; Herrmann, Enrico ; Litsey, Sean ; Stankowicz, James ; et al
The dual formulation of planar N = 4 $$ \mathcal{N}=4 $$ superYangMills scattering amplitudes makes manifest that the integrand has only logarithmic singularities and no poles at infinity. [...]
