Towards a Numerical Implementation of the Loop-Tree Duality Method

Understand

We review the recent progress on the numerical implementation of the Loop-Tree Duality Method (LTDM) for the calculation of scattering amplitudes.

• A central point is the analysis of the singularities of the integrand.
• In the framework of the LTDM some of these singularities cancel out.
• The ones left over are dealt with by contour deformation.
