In the forthcoming high luminosity phase of the LHC many of the most interesting measurements for precision QCD studies are affected by large pile-up conditions. However, with the recently discovered Higgs boson, which couples in the heavy top limit directly to gluons, we have access to a novel production process to probe QCD by a colour-singlet current. In this study we compare observables in Higgs boson and Drell-Yan production and evaluate their stability with respect to pile-up effects. We present first attempts to apply various pile-up correction methods both to underlying event and to boson + jet event topologies, and compare Pythia8, Powheg and CASCADE event generator predictions to demonstrate the sensitivity to different multiple-parton radiation mechanisms.
