Description

In both single top and VBF Higgs production a structure function approximation can be applied to obtain the leading colour contribution. This approximation contains only so-called factorisable diagrams and is exact at NLO. However, at NNLO non-factorisable contributions come into play. A particular challenge for calculations at this order is the evaluation of two-loop diagrams with several mass scales. In this talk I will present calculations and results for the phenomenological impact of non-factorisable contributions in t-channel single top and VBF Higgs production.
