The Cut Equation
Nima Arkani-Hamed, Hadleigh Frost, Giulio Salvatori
Scattering amplitudes for colored theories have recently been formulated in a new way, in terms of curves on surfaces. In this note we describe a canonical set of functions we call…

The Tropical Geometry of Subtraction Schemes
Giulio Salvatori
We study the construction of local subtraction schemes through the lenses of tropical geometry. We focus on individual Feynman integrals in parametric presentation, and think of th…

Tropical Amplitudes For Colored Lagrangians
Nima Arkani-Hamed, Carolina Figueiredo, Hadleigh Frost +1
Recently a new formulation for scattering amplitudes in Tr() theory has been given based on simple combinatorial ideas in the space of kinematic data. This allows all-loop int…
