A data-driven QCD background estimate in ATLAS searches for heavy Wh resonances in the final state ℓν b b — •Andreas Hönle, Sandra Kortner, Hubert Kroha, and Felix Müller — Max-Planck-Institut für Physik

Many extensions of the Standard Model (SM) predict the existence of heavy resonances that decay into boson pairs. A promising channel is the decay of a heavy W′ resonance into a charged SM vector boson W and the SM Higgs boson h, followed by a semi-leptonic decay into the final state ℓ ν b b. Multijet background, originating from QCD processes, is difficult to describe with Monte Carlo simulations and is thus particularly challenging to model. In this talk, two data-driven methods to estimate this background are presented: the Template Method and the ABCD method.
