Abstract:

The total decay width of the Higgs has not yet been constrained precisely from the current measurement of the Higgs boson coupling to other standard model particles, which allows for up to 30% of the Higgs decays to come from BSM processes. If sufficiently light, dark matter particles may be produced in decays of the Higgs bosons leading to invisible final states. The Vector Boson Fusion (VBF) production mechanism of the Higgs boson provides a distinctive signature of two jets that are largely separated in pseudorapidity that can be used to target events with invisible Higgs decays, where particles invisible to the detector are a source of missing transverse momentum. The most recent ATLAS results of VBF-produced Higgs bosons decaying invisibly will be presented, using the full Run-2 dataset of 139/fb of 13 TeV center-of-mass proton--proton collisions. Further interpretations set limits on the VBF production of other heavy scalars, and the WIMP-nucleon cross-section.
