Combination of searches for strongly-produced supersymmetric particles with the ATLAS detector in proton-proton collision data at $\sqrt{s}$=8 TeV

This note presents the combination of three ATLAS searches for squarks and gluinos in 20 $fb^{−1}$ of proton-proton collisions at $\sqrt{s}$=8 TeV. The results of searches in final states with jets, missing transverse momentum and no or one isolated lepton are combined and interpreted in a simplified model where pair-produced squarks or gluinos decay through an intermediate chargino to the lightest stable supersymmetrical particle. In the model of pair-produced gluinos, gluinos below 1.3 TeV are excluded at 95% CL, for a neutralino mass below 500 GeV. Squarks are excluded up to 850 GeV at 95% CL for massless neutralinos. These limits are an improvement of approximately 50 GeV with respect to the results of the separate analyses.
