A summary is presented of ATLAS searches for gluinos and first- and secondgeneration squarks in final states containing jets and missing transverse momentum, with or without leptons or b-jets, in the root s = 8TeV data set collected at the Large Hadron Collider in 2012. This paper reports the results of new interpretations and statistical combinations of previously published analyses, as well as a new analysis.
Since no significant excess of events over the Standard Model expectation is observed, the data are used to set limits in a variety of models. In all the considered simplified models that assume R-parity conservation, the limit on the gluino mass exceeds 1150 GeV at 95% confidence level, for an LSP mass smaller than 100 GeV.
