Exposing the threshold structure of loop integrals
Zeno Capatti
The understanding of the physical laws determining the infrared behaviour of amplitudes is a longstanding and topical problem. In this paper, we show that energy conservation alone…

Flow-oriented perturbation theory
Michael Borinsky, Zeno Capatti, Eric Laenen +1
We introduce a new diagrammatic approach to perturbative quantum field theory, which we call flow-oriented perturbation theory (FOPT). Within it, Feynman graphs are replaced by str…

Local Unitarity: cutting raised propagators and localising renormalisation
Zeno Capatti, Valentin Hirschi, Ben Ruijl
The Local Unitarity (LU) representation of differential cross-sections locally realises the cancellations of infrared singularities predicted by the Kinoshita-Lee-Nauenberg theorem…
