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…
Local Unitarity
Zeno Capatti
Within the Local Unitarity formalism, any physical cross-section is re-written in such a way that cancellations of infrared singularities between real and virtual contributions are…
Manifestly Causal Loop-Tree Duality
Zeno Capatti, Valentin Hirschi, Dario Kermanschah +2
Loop-Tree Duality (LTD) is a framework in which the energy components of all loop momenta of a Feynman integral are integrated out using residue theorem, resulting in a sum over tr…
Numerical Loop-Tree Duality: contour deformation and subtraction
Zeno Capatti, Valentin Hirschi, Dario Kermanschah +2
We introduce a novel construction of a contour deformation within the framework of Loop-Tree Duality for the numerical computation of loop integrals featuring threshold singulariti…
Loop Tree Duality for multi-loop numerical integration
Zeno Capatti, Valentin Hirschi, Dario Kermanschah +1
Loop Tree Duality (LTD) offers a promising avenue to numerically integrate multi-loop integrals directly in momentum space. It is well-established at one loop, but there have been…
