Resumen:
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 8 TeV using
the ATLAS detector at the LHC. The search is performed separately in
events with either zero or at least one high-p T
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.
