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…

Tropical sampling from Feynman measures
Michael Borinsky, Mathijs Fraaije
We introduce an algorithm that samples a set of loop momenta distributed as a given Feynman integrand. The algorithm uses the tropical sampling method and can be applied to evaluat…

Light-by-Light Scattering at Next-to-Leading Order in QCD and QED
Ajjath A H, Ekta Chaubey, Mathijs Fraaije +2
The recent experimental observation of Light-by-Light (LbL) scattering at the Large Hadron Collider has revived interest in this fundamental process, and especially of the accurate…
