Description
In this talk, I will present the nested soft-collinear approach to the long-standing issue of infrared subtraction at next-to-next-to-leading order in QCD. At this order in perturbation theory, the structure of infrared singularities is rather clear. However, a fully general method for combining virtual and real emission singularities yielding predictions for physical observables is only now starting to be available for generic processes. I will delve into the nested soft-collinear approach from its first implementations for color singlet production to its most recent efforts toward a generalization to more complex processes.
