Search for chargino–neutralino pair production in final states with three leptons and missing transverse momentum in $$$$\sqrt{s} = 13$$$$ TeV pp collisions with the ATLAS detector
Journal Article·· European Physical Journal. C, Particles and Fields
A search for chargino–neutralino pair production in three-lepton final states with missing transverse momentum is presented. The study is based on a dataset of $$\sqrt{s}$$=13 TeV pp collisions recorded with the ATLAS detector at the LHC, corresponding to an integrated luminosity of 139 fb-1. No significant excess relative to the Standard Model predictions is found in data. The results are interpreted in simplified models of supersymmetry, and statistically combined with results from a previous ATLAS search for compressed spectra in two-lepton final states. Various scenarios for the production and decay of charginos ($$\tilde{χ}^±_1$$) and neutralinos ($$\tilde{χ}^0_2$$) are considered. For pure higgsino $$\tilde{χ}^±_1$$$$\tilde{χ}^0_2$$ pair-production scenarios, exclusion limits at 95% confidence level are set on $$\tilde{χ}^0_2$$ masses up to 210 GeV. Limits are also set for pure wino $$\tilde{χ}^±_1$$$$\tilde{χ}^0_2$$ pair production, on $$\tilde{χ}^0_2$$ 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.
