13:00 → 14:00 Measurement of off-shell Higgs boson production in the H->ZZ channel with the ATLAS detector

We will review the most recent measurements of the off-shell Higgs boson production in the H->ZZ channel with the ATLAS detector. The production was probed using both H->ZZ->4l and H->ZZ->2l2nu decay modes. We will review the techniques used in each decay channel, the systematic model used, and how they compare to other measurements of the off-shell Higgs boson production. We will describe how this measurement has been used to probe new physics that could modify the production of Higgs bosons at virtuality.
