Proving the dimension-shift conjecture
Ruth Britto, Guy R. Jehu, Andrea Orta
We prove the conjecture made by Bern, Dixon, Dunbar, and Kosower that describes a simple dimension shifting relationship between the one-loop structure of N = 4 MHV amplitudes and…
The dimension-shift conjecture for one-loop amplitudes
Ruth Britto, Guy R. Jehu, Andrea Orta
A conjecture made by Bern, Dixon, Dunbar, and Kosower asserts a simple dimension-shifting relationship between the one-loop structure of N = 4 MHV amplitudes and all-plus helicity…
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…
Towards the Amplituhedron Volume
Livia Ferro, Tomasz Lukowski, Andrea Orta +1
It has been recently conjectured that scattering amplitudes in planar N=4 super Yang-Mills are given by the volume of the (dual) amplituhedron. In this paper we show some interesti…
