Description
Diboson production processes constitute an interesting probe of New Physics related to the Higgs boson and the EW sector. We revisit the 𝑊ℎ and 𝑍ℎ production processes, with ℎ→𝑏𝑏¯ and leptonically decaying gauge bosons. For the first time, we include the neutrino decay channel of the Z boson and perform a scale-invariant b-tagging. We study these processes in the SMEFT framework and derive bounds on four dimension-6 operators at LHC Run 2, Run 3 and HL-LHC. We show how most of our sensitivity comes from the events with a boosted Higgs. We also present projections for the bounds from these channels at FCC-hh and compare with previous results obtained for the case of ℎ→𝛾𝛾.
