Abstract: The results of a search for strong production of supersymmetric particles inmulti-b-jets final states in 20.1 fb􀀀1 of pp collisions atps = 8 TeV using the ATLASdetector at the LHC are reported. This search is performed in events with zero orat least one lepton (electron or muon), large missing transverse momentum, at leastfour, six or seven jets and at least three jets tagged as originating from b-quarks. Noexcess is observed in data with respect to the Standard Model predictions. Resultsare interpreted in the context of several supersymmetric models involving gluinosand 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, whichsignificantly extends the previous ATLAS results.
