dc.description.abstract | Asearch for chargino–neutralino pair production in three-lepton final states with missing transverse momentum is presented. The study is based on a dataset of √ s = 13 TeV pp collisions recorded with the ATLAS detector at the LHC, corresponding to an integrated luminosity of 139 fb−1. No significant excess relative to the Standard Model predictions is found in data. The results are interpreted in simplified models of supersymmetry, and statistically combined with results from a previous ATLAS search for compressed spectra in two-lepton final states. Various scenarios for the production and decay of charginos (˜χ ± 1 ) and neutralinos (˜χ 0 2 ) are considered. For pure higgsino ˜χ ± 1 ˜χ 0 2 pairproduction scenarios, exclusion limits at 95% confidence level are set on ˜χ 0 2 masses up to 210 GeV. Limits are also set for pure wino ˜χ ± 1 ˜χ 0 2 pair production, on ˜χ 0 2 masses up to 640 GeV for decays via on-shell W and Z bosons, up to 300 GeV for decays via off-shell W and Z bosons, and up to 190 GeV for decays via W and Standard Model Higgs bosons. | pt |
