Search for Diboson Resonances (X —→ Zh,Wh) produced via Vector Boson Fusion with the ATLAS Detector. — •Stefan Maschek, Dominik Duda, Andreas Hönle, Sandra Kortner und Hubert Kroha für die ATLAS Kollaboration — Max-Planck-Institut für Physik, München

The heavy vector triplet (HVT) model summarizes several extensions of the Standard Model into one phenomenological Lagrangian and predicts heavy vector bosons Z’ and W’, which can decay into the Standard Model Higgs boson h and SM vector boson Z or W. In some regions of the model parameter space, the couplings to fermions are forbidden such that the production of these new hypothetical particles via the fusion of two vector bosons (VBF) becomes the dominant production process.

In this production mode, the two quarks that each irradiate a vector boson, will form hadron showers in opposite hemispheres in the forward region of the ATLAS detector, resulting in a large gap in the pseudorapidity of those two jets.

This talk will present the results of a search for the Vh (V=W,Z) resonances produced via the vector boson fusion. The studies in this final state are performend for the first time in ATLAS.
