Numerical integration of loop integrals through local cancellation of threshold singularities
Dario Kermanschah
We propose a new approach that allows for the separate numerical calculation of the real and imaginary parts of finite loop integrals. We find that at one-loop the real part is giv…
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…
