Description
Loop Tree Duality (LTD) offers a promising avenue to numerically
integrate multi-loop integrals directly in momentum space by relating
them to on-shell trees.
I will first present our novel formulation of this duality, applicable
systematically and for generic multi-loop integrals.
I will then showcase our first numerical results for up to four-loop
finite scalar topologies, and conclude by discussing our ongoing work
regarding applications to physical loop amplitudes that require an
adequate contour deformation and local subtraction of its IR
divergences
