Description
In this talk, I discuss non-factorizable loop contributions entering the NNLO QCD prediction for Higgs boson production via vector boson fusion at the LHC. Firstly, I present a calculation of the one-loop amplitude to higher orders in the dimensional regulator $\varepsilon$, which is required for infrared subtraction terms. Secondly, for two of the relevant two-loop five-point Feynman integral families, I discuss the construction of canonical differential equations and a first numerical implementation.
