Search for heavy Vh resonances with the ATLAS detector in the final state with boosted h → bb decays — •Andreas Hönle, Dominik Duda, Sandra Kortner, Hubert Kroha, and Stefan Maschek — Max-Planck-Institut für Physik
Many extensions of the Standard Model (SM) predict the existence of heavy resonances that decay into boson pairs. A process with promising search prospects is the decay of a heavy particle into a SM vector boson V (≡ W, Z) and the SM Higgs boson h with a subsequent leptonic V decay and a Higgs boson decay into a pair of b quarks.
With the final Run 2 ATLAS dataset of 139 fb−1, recorded at √s = 13 TeV, this process can be probed in new regions of phase space which were not accessible before.
This talk presents most recent results from the search for Vh resonances in the semileptonic decay channel based on the full Run 2 ATLAS dataset.
