QCD Corrections to W and Z Production via Vector Boson Fusion in the Powheg-Box — •Franziska Schissler and Dieter Zeppenfeld — Institut für Theoretische Physik, Karlsruher Institut für Technologie (KIT), 76128 Karlsruhe
We present the implementation of electroweak Zjj and Wjj production via vector boson fusion with fully leptonic decays at NLO QCD in the Powheg framework. These processes represent an important background to Higgs searches in vector boson fusion, but can also be seen as signal processes to study for example the impact of a central jet veto. Observables related to the third jet are sensitive to the parton shower being used, which is demonstrated by a comparison between Pythia, the standard angular-ordered Herwig++ shower and its new pT-ordered Dipole Shower.
