The CEGM NLSM
Nick Early
Studying quantum field theories through geometric principles has revealed deep connections between physics and mathematics, including the discovery by Cachazo, Early, Guevara and M…
Positive del Pezzo Geometry
Nick Early, Alheydis Geiger, Marta Panizzut +2
Real, complex, and tropical algebraic geometry join forces in a new branch of mathematical physics called positive geometry. We develop the positive geometry of del Pezzo surfaces…
Generalized Color Orderings: CEGM Integrands and Decoupling Identities
Freddy Cachazo, Nick Early, Yong Zhang
In a recent paper, we defined generalized color orderings (GCO) and Feynman diagrams (GFD) to compute color-dressed generalized biadjoint amplitudes. In this work, we study the Cac…
Color-Dressed Generalized Biadjoint Scalar Amplitudes: Local Planarity
Freddy Cachazo, Nick Early, Yong Zhang
The biadjoint scalar theory has cubic interactions and fields transforming in the biadjoint representation of . Amplitudes are "colo…
Factorization for Generalized Biadjoint Scalar Amplitudes via Matroid Subdivisions
Nick Early
We study the problem of factorization for residues of generalized biadjoint scalar scattering amplitudes , introduced by Cachazo, Early, Guevara and Mizera (CEGM), invol…
Biadjoint Scalars and Associahedra from Residues of Generalized Amplitudes
Freddy Cachazo, Nick Early
In the Grassmannian formulation of the S-matrix for planar Super Yang-Mills, scattering amplitudes for negative and positive helicity gluons…
