Abstract:

The results of a search for direct pair production of top squarks in events with two opposite-charge leptons (electrons or muons) are reported, using 36.1 fb^-1 of integrated luminosity from proton鈥損roton collisions at 鈭歴 = 13 TeV collected by the ATLAS detector at the Large Hadron Collider. To cover a range of mass differences between the top squark t藴 and lighter supersymmetric particles, four possible decay modes of the top squark are targeted with dedicated selections: the decay t藴 鈫 b 蠂藴卤1 into a b-quark and the lightest chargino with 蠂藴卤1 鈫 W蠂藴01, the decay t藴 鈫 t 蠂藴01 into an on-shell top quark and the lightest neutralino, the three-body decay t藴 鈫 bW 蠂藴01 and the four-body decay t藴 鈫 b`饾搧v蠂藴01 . No significant excess of events is observed above the Standard Model background for any selection, and limits on top squarks are set as a function of the t藴 and 蠂藴01 masses. The results exclude at 95% confidence level 蠂藴01 masses up to about 720 GeV, extending the exclusion region of supersymmetric parameter space covered by previous searches.
