Search for top squark pair production in final states with two leptons at LHC Run 2 with the ATLAS detector

Although no experimental evidence has been found during LHC Run1, Supersymmetry (SUSY) remains one of the most promising and motivated Standard Model (SM) extensions. Focusing the attention on models where the multiplicative quantum number R-parity is conserved, the latest results in searching for pair production of top squarks decaying to a bottom quark and the lightest chargino or to a top quark and the lightest supersymmetric particle (neutralino) in final states with 2 leptons are presented, using proton-proton collision data collected by the ATLAS experiment during 2015 and 2016 at a center-of-mass energy of 13 TeV and corresponding to an integrated luminosity of 36.1 fb\$^{-1}\$. Each of the decay modes is searched in the context of a simplified model, assuming a branching ratio of 100% for both signals
