Content
In this talk we present the first proof-of-concept of the application of the Causal Unitarity formalism, based on the manifestly causal Loop-Tree Duality, to decay processes at NLO. Furthermore, we provide a physical interpretation of the local cancellation of soft, collinear and unitary threshold singularities, and of the local renormalization of ultraviolet singularities.
