Content
In this talk, we will discuss about recent developments concerning efficient calculations of multi-loop multi-leg scattering amplitudes. Inspired by the nice properties of the Loop-Tree Duality (LTD), we explain how to reconstruct an integrand level representation of scattering amplitudes which only contains physical singularities. The so-called causal representations can be originated from connected binary partitions of Feynman diagrams, properly entangled according certain rules. We will explain these rules and present some illustrative examples.
