A mathematical perspective on nonplanar on-shell forms
Artyom Lisitsyn, Elizabeth Pratt, Melissa Sherman-Bennett +1
On-shell forms are differential forms on the Grassmannian which arise in particle physics. They are defined using bipartite graphs with distinguished ``boundary'' vertices. Mat…
Multi-Loop Negative Geometries
Lance J. Dixon, Umut Oktem, Shruti Paranjape +3
Scattering amplitudes in planar supersymmetric Yang-Mills theory are dual to expectation values of null polygonal Wilson loops. The Amplituhedron provides a geometric…
A Surface Integrand for the Inverse KLT Kernel
Christoph Bartsch, Karol Kampf, Jiří Novotný +1
We propose a loop-level generalization of the inverse string theory Kawai-Lewellen-Tye (KLT) kernel: the planar inverse KLT integrand. The integrand is defined constructively via a…
