Search for a supersymmetric top-quark partner in final states with two leptons in sqrt(s) = 8 TeV pp collisions using 13 ifb of ATLAS data

The results of a search for direct pair production of supersymmetric partners of the top quark in 13.0 \ifb\ of integrated luminosity from LHC $pp$ collisions at 8~\TeV\ collected by the ATLAS detector are reported. Scalar tops decaying into a $b$ quark and a chargino are sought for in events with t...

description The results of a search for direct pair production of supersymmetric partners of the top quark in 13.0 \ifb\ of integrated luminosity from LHC $pp$ collisions at 8~\TeV\ collected by the ATLAS detector are reported. Scalar tops decaying into a $b$ quark and a chargino are sought for in events with two leptons in the final state. No excess above the Standard Model expectation is observed. A scalar top quark with mass between 150 and 450 GeV is excluded at 95\% confidence level for a chargino approximately degenerate in mass with the \scalartop and a massless lightest neutralino.
