This paper reports the results of a search for strong production of supersymmetric
particles in 20.1 fb−1 of proton-proton collisions at a centre-of-mass energy of 8TeV
using the ATLAS detector at the LHC. The search is performed separately in events with
either zero or at least one high-pT lepton (electron or muon), large missing transverse
momentum, high jet multiplicity and at least three jets identified as originated from the
fragmentation of a b-quark. No excess is observed with respect to the Standard Model
predictions. The results are interpreted in the context of several supersymmetric models
involving gluinos and scalar top and bottom quarks, as well as a mSUGRA/CMSSM
model. Gluino masses up to 1340 GeV are excluded, depending on the model, significantly
extending the previous ATLAS limits.
