Spin-2 Resonances in Vector Boson Fusion at the LHC — •Jessica Frank, Michael Rauch, and Dieter Zeppenfeld — IThP, Karlsruhe Institute of Technology, 76128 Karlsruhe, Germany

In this talk we present the production of spin-2 resonances in vectorboson fusion at the LHC. We start from an effective Lagrangian of the interaction of a spin-2 particle with electroweak gauge bosons and derive the corresponding Feynman rules. Thereby we consider two different scenarios: heavy spin-2 resonances which decay into two gauge bosons, leading to a four-lepton final state, and light Higgs-like resonances producing two photons. These processes have been implemented into the Monte Carlo program VBFNLO.

Our analysis focuses on angular correlations, as they are known as a powerful tool to study the spin of a resonance. We investigate how we can use them to establish, or disprove, the spin-2 nature of such states, and distinguish these from Higgs bosons.
