Abstract: Abstract The amplituhedron determines scattering amplitudes in planar $$ \mathcal{N} $$ N = 4 super Yang-Mills by a single “positive geometry” in the space of kinematic and loop variables. We study a closely related definition… read more here.

Abstract: A bstractThe maximally helicity violating (MHV) amplitudes of N=4$$ \mathcal{N}=4 $$ super Yang-Mills theory at strong coupling are obtained by solving auxiliary thermodynamic Bethe ansatz (TBA) integral equations. We consider a limit where the TBA… read more here.
