Thanks to a remarkable progress in understanding of how to perform NNLO QCD computations, many processes at hadron collisions have been recently computed to that precision. Despite these developments, the search for the optimal subtraction scheme that allows us to handle infrared and collinear singularities in an efficient and general way is still ongoing. In the following, I will review the nested soft–collinear subtraction scheme proposed in F. Caola, K. Melnikov, R. Röntsch, Eur. Phys. J. C 77, 248 (2017). This scheme seems to possess many features of the possible optional scheme; for example, it is analytic, fully local and highly modular. I will describe an application of this scheme to the description of deep inelastic scattering of a proton with an electron (DIS) that, together with results on colour singlet production and decay, completes the set of building blocks that are required for the application of this scheme to arbitrary processes at hadron colliders.
