A Task Force on Strong Coupling Determinations from Event Shapes
Anthony Badea, Luca Buonocore, Gherardo Vita +19
The strong coupling constant is a fundamental parameter of the Standard Model. Its precise determination is essential for accurately predicting, studying, and understanding p…
NNLO QCD corrections to from Local Unitarity combined with Coulomb resummation and NLO EW effects
Zeno Capatti, Mathijs Fraaije, Valentin Hirschi +3
The Local Unitarity (LU) formalism provides a constructive, integrand-level realisation of the Kinoshita-Lee-Nauenberg (KLN) theorem, by combining loop and phase-space integrals ap…
Multi-partonic interactions, iterated discontinuities and the virtuality expansion in deep inelastic scattering
Zeno Capatti, Lucien Huber, Michael Ruf
We introduce a perturbative model that accounts for the contribution of multi-partonic interactions to collider observables. A key feature of this multi-parton model is that cross…
Derivation of the Cross-Free Family representation for the box diagram
Zeno Capatti
I work out in full detail the derivation of the Cross-Free Family (CFF) representation for the box diagram, and highlight the differences with its Time Ordered Perturbation Theory…
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…
Local Unitarity: a representation of differential cross-sections that is locally free of infrared singularities at any order
Zeno Capatti, Valentin Hirschi, Andrea Pelloni +1
We propose a novel representation of differential scattering cross-sections that locally realises the direct cancellation of infrared singularities exhibited by its so-called real-…
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…
