 Title: Search for electroweak production of supersymmetric particles in final states with two or three leptons at ?s = 13 TeV with the ATLAS detector Authors: The ATLAS CollaborationSultansoy, Saleh Keywords: Collisions jets proton–proton collisions Issue Date: 2018 Publisher: Springer New York LLC Source: ATLAS collaboration. (2018). Search for electroweak production of supersymmetric particles in final states with two or three leptons at $$\sqrt {s}= 13\hbox {TeV}$$ with the ATLAS detector. The European Physical Journal C, 78(12), 995. Abstract: A search for the electroweak production of charginos, neutralinos and sleptons decaying into final states involving two or three electrons or muons is presented. The analysis is based on 36.1 fb?1 of ?s = 13 TeV proton– proton collisions recorded by the ATLAS detector at the Large Hadron Collider. Several scenarios based on simplified models are considered. These include the associated production of the next-to-lightest neutralino and the lightest chargino, followed by their decays into final states with leptons and the lightest neutralino via either sleptons or Standard Model gauge bosons; direct production of chargino pairs, which in turn decay into leptons and the lightest neutralino via intermediate sleptons; and slepton pair production, where each slepton decays directly into the lightest neutralino and a lepton. No significant deviations from the Standard Model expectation are observed and stringent limits at 95% confidence level are placed on the masses of relevant supersymmetric particles in each of these scenarios. For a massless lightest neutralino, masses up to 580 GeV are excluded for the associated production of the next-to-lightest neutralino and the lightest chargino, assuming gauge-boson mediated decays, whereas for slepton-pair production masses up to 500 GeV are excluded assuming three generations of mass-degenerate sleptons. © CERN for the benefit of the ATLAS collaboration 2018.
