Search for supersymmetric scalar leptons at the LHC Run 2 with the ATLAS detector

Here we present an analysis of the progress on the data collected by the ATLAS detector at the LHC collider at $√s= 13 TeV$. The goal is to observesupersymmetric particles and, in particular, the direct pair production of scalar leptons. The scalar leptons decay into leptons and neutralinos. The final state contains two leptons, no hadronic activity and a large missing transverse momentum.
