Description

SUperSYmmetry (SUSY) is one of the most promising extensions of the Standard Model. 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. They have been obtained on 139 fb$^{-1}$ proton-proton collisions recorded by the ATLAS detector at the Large Hadron Collider at $\sqrt s$ = 13 TeV. Three scenarios, based on simplified models, are considered: the production of lightest chargino pairs, followed by their decays into final states with leptons and the lightest neutralino via either sleptons or W bosons; direct production of slepton pairs, where each slepton decays directly into the lightest neutralino and a lepton. No significant deviations from the Standard Model expectations are observed and stringent limits at 95$\%$ confidence level are set on the masses of relevant supersymmetric particles in each of these scenarios.
