-Algebra and Scattering Amplitudes
Freddy Cachazo, Nick Early, Alfredo Guevara +1
In this paper we study an algebra that naturally combines two familiar operations in scattering amplitudes: computations of volumes of polytopes using triangulations and constructi…
Feynman Integrals and Intersection Theory
Pierpaolo Mastrolia, Sebastian Mizera
We introduce the tools of intersection theory to the study of Feynman integrals, which allows for a new way of projecting integrals onto a basis. In order to illustrate this techni…
Perturbiner Methods for Effective Field Theories and the Double Copy
Sebastian Mizera, Barbara Skrzypek
Perturbiner expansion provides a generating function for all Berends-Giele currents in a given quantum field theory. We apply this method to various effective field theories with a…
The S Matrix of 6D Super Yang-Mills and Maximal Supergravity from Rational Maps
Freddy Cachazo, Alfredo Guevara, Matthew Heydeman +3
We present new formulas for -particle tree-level scattering amplitudes of six-dimensional super Yang-Mills (SYM) and supergravity (SUGRA)…
