Application of the nested soft-collinear subtraction scheme to the description of deep inelastic scattering

Recently, remarkable progress was made in the understanding of how fully-differential nextto- next-to-leading order (NNLO) computations in perturbative Quantum Chromodynamics (QCD) for hadron collider processes can be performed. This progress includes development of promising subtraction schemes that allow us to treat infrared and collinear singularities efficiently. As the result of these developments, many phenomenologically important processes at hadron colliders have been computed with NNLO QCD accuracy. However, despite this progress, the search for the optimal subtraction scheme continues. In this thesis we discuss the recently proposed nested soft-collinear subtraction scheme and apply it to the description of deep inelastic scattering of an electron on a proton. Our results provide an important building block that will allow for description of more complex processes at hadronic colliders in a fully differential manner, using the nested soft-collinear subtraction scheme.
