Non-planar BCFW Grassmannian Geometries
Shruti Paranjape, Jaroslav Trnka, Minshan Zheng
In this paper, we study non-adjacent BCFW recursion relations and their connection to positive geometry. For an adjacent BCFW shift, the -point NMHV tree-level amplitude in…
Integrands of Less-Supersymmetric Yang-Mills at One Loop
Jacob L. Bourjaily, Enrico Herrmann, Cameron Langer +3
We construct a prescriptive, bubble power-counting basis of one-loop integrands suitable for representing amplitude integrands in less-supersymmetric Yang-Mills theory. With the ex…
Positive geometry, local triangulations, and the dual of the Amplituhedron
Enrico Herrmann, Cameron Langer, Jaroslav Trnka +1
We initiate the systematic study of \emph{local positive spaces} which arise in the context of the Amplituhedron construction for scattering amplitudes in planar maximally supersym…
Positive Geometries for One-Loop Chiral Octagons
Enrico Herrmann, Cameron Langer, Jaroslav Trnka +1
Inspired by the topological sign-flip definition of the Amplituhedron, we introduce similar, but distinct, positive geometries relevant for one-loop scattering amplitudes in planar…
