Duals of Feynman Integrals. Part II. Generalized unitarity
Abstract The first paper of this series introduced objects (elements of twisted relative cohomology) that are Poincaré dual to Feynman integrals. We show how to use the pairing between these spaces — an algebraic invariant called the intersection number — to express a scattering amplitude over a min...
