Tree-level scattering amplitudes from the amplituhedron
Livia Ferro, Tomasz Lukowski, Andrea Orta +1
A central problem in quantum field theory is the computation of scattering amplitudes. However, traditional methods are impractical to calculate high order phenomenologically relev…

Yangian Symmetry for the Tree Amplituhedron
Livia Ferro, Tomasz Lukowski, Andrea Orta +1
Tree-level scattering amplitudes in planar N=4 super Yang-Mills are known to be Yangian-invariant. It has been shown that integrability allows to obtain a general, explicit method…
