Constraining off-shell Higgs boson production and the Higgs boson total width using WWRIGHTWARDS ARROW (l, l) final states with the ATLAS detector
Original language description
A measurement of off-shell Higgs boson production is performed in the H-* -> W Wchannel. The measurement uses a proton-proton collision dataset with an integrated luminosity of 140 fb(-1) collected at a centre-of-mass energy of 13 TeV by the ATLAS detector at the Large Hadron Collider. Final states in which both.. bosons decay leptonically are targeted, and events are categorised based on the flavour of the final-state leptons, the jet multiplicity, and the output of neural network-based classifiers. The data are found to be compatible with the Standard Model expectation. An observed (expected) upper bound on the 95% symmetric confidence level interval is set on the rate of off-shell Higgs boson production at a value of 3.4 (4.4) times the Standard Model prediction. These results are combined with the results from the measurement of on-shell Higgs boson production in the same final states to obtain an observed (expected) upper bound at 95% confidence level on the Higgs boson total width of 13.1 (17.3) MeV.
