Parton-Shower Effects in QCD-VVjj Production with Leptonic Decays — •Christophe Theiß and Michael Rauch — ITP/KIT, Karlsruhe, Deutschland

The production of vector bosons plus two jets is an important signature at the LHC. QCD Production, i.e. at O(α_s²), is the leading contribution to these processes. Also when studying electroweak production via vector-boson fusion (VBF), the corresponding QCD process is the main background and yields sizable contributions even after placing typical VBF cuts. Therefore, precise predictions for these processes are necessary.

In this talk, we present the combination of NLO QCD results with parton showers for VVjj processes, including leptonic decays as well as off-shell and non-resonant contributions. To that end, we have extended the NLO QCD implementation in VBFNLO to provide an interface to parton showers via the Binoth Les Houches Accord. We discuss some details of the implementation and show results when combining with the Herwig 7 event generator.
