Connecting Scalar Amplitudes using The Positive Tropical Grassmannian
Freddy Cachazo, Bruno Giménez Umbert
The biadjoint scalar partial amplitude, , can be expressed as a single integral over the positive tropical Grassmannian thus producing a Global Schwinge…
Smoothly Splitting Amplitudes and Semi-Locality
Freddy Cachazo, Nick Early, Bruno Umbert
In this paper, we study a novel behavior developed by certain tree-level scalar scattering amplitudes, including the biadjoint, NLSM, and special Galileon, when a subset of kinemat…
Planar Matrices and Arrays of Feynman Diagrams
Freddy Cachazo, Alfredo Guevara, Bruno Umbert +1
Very recently planar collections of Feynman diagrams were proposed by Borges and one of the authors as the natural generalization of Feynman diagrams for the computation of b…
Singular Solutions in Soft Limits
Freddy Cachazo, Bruno Umbert, Yong Zhang
A generalization of the scattering equations on , the configuration space of points on , to higher dimensional projective spaces was recently introduced…
