Description

Recent results from a search for the electroweak production of charginos and sleptons decaying into final states with two leptons (electrons and/or muons) are presented on 139 $\text{fb}^{-1}$ proton-proton collision data recorded by the ATLAS detector at the Large Hadron Collider at $\sqrt{s} = 13$ TeV. Three different R-parity conserving scenarios, based on simplified models, are considered: the direct production of lightest chargino pairs, followed by their decays into final states with leptons and the lightest neutralino via either W bosons or sleptons/sneutrinos; the direct production of slepton pairs, where each slepton decays into the lightest neutralino and a lepton. No significant deviations from the Standard Model expectations are observed and limits at 95% confidence level are set on the masses of the relevant supersymmetric particles in each of these scenarios.
