Tree-level scattering amplitudes from the amplituhedron

Understand

A central problem in quantum field theory is the computation of scattering amplitudes.

• However, traditional methods are impractical to calculate high order phenomenologically relevant observables.
• Building on a few decades of astonishing progress in developing non-standard computational techniques, it has been recently conjectured that amplitudes in planar N=4 super Yang-Mills are given by the volume of the (dual) amplituhedron.
• After providing an introduction to the subject at tree-level, we discuss a special class of differential equations obeyed by the corresponding volume forms.
