Search for Supersymmetry in Leptonic Final States with the ATLAS Detector — •Marian Rendel, Michael Holzbock, Hubert Kroha, and Sandra Kortner — Max-Planck-Institut für Physik (Werner-Heisenberg-Institut), München)

Supersymmetry (SUSY) is one of the best studied extensions of the Standard Model (SM) and as such the search for SUSY is a major part of the ATLAS physics program. A SUSY models with scalar partners of the SM leptons (sleptons) may address the muon g-2 anomaly, as well as provide a viable candidate for Dark matter, and are thus of particular interest. Due to their low production cross section and the high Standard Model (SM) background, the search for sleptons is challenging. This motivates to employ multivariate methods to distinguish between SUSY and the SM background. In this talk a search for sleptons in events with two same-flavor opposite-sign leptons and initial state radiation topology is presented which uses 139 fb⁻¹ LHC proton-proton collision data collected by the ATLAS experiment during the years 2015 and 2018.
