Search for strong production of supersymmetric particles in final states with missing transverse momentum and at least three b-jets using 20.1 fb−1 of pp collisions at sqrt(s) = 8 TeV with the ATLAS Detector.

The results of a search for strong production of supersymmetric particles in multi-$b$-jets final states in 20.1 fb$^{-1}$ of $pp$ collisions at $\sqrt{s}=8$ TeV using the ATLAS detector at the LHC are reported. This search is performed in events with zero or at least one lepton (electron or muon), large missing transverse momentum, at least four, six or seven jets and at least three jets tagged as originating from $b$-quarks. No excess is observed in data with respect to the Standard Model predictions. Results are interpreted in the context of several supersymmetric models involving gluinos and top and bottom squarks, and in the context of a mSUGRA/CMSSM model. Gluino masses up to about 1.3 TeV are excluded, depending on the model, which significantly extends the previous ATLAS results.
