From Feynman diagrams to the amplituhedron: a gentle review
Shounak De, Dmitrii Pavlov, Marcus Spradlin +1
In this article we review, for a mathematical audience, the computation of (tree-level) scattering amplitudes in Yang-Mills theory in detail, in order to bridge the gap in understa…

Surfaceology for Colored Yukawa Theory
Shounak De, Andrzej Pokraka, Marcos Skowronek +2
Arkani-Hamed and collaborators have recently shown that scattering amplitudes for colored theories can be expressed as integrals over combinatorial objects simply constructed from…
