Abstract (data abstract)
CERN-LHC. Study of events from proton-proton interactions at a centre-of-mass energy of 7 TeV which have final states comprising exclusively one or two leptons (either electrons or muons), large missing transverse momentum, light flavour jets and b-jets. The data sample used has an integrated luminosity of 4.7 fb-1. The data are analysed in the framework of MSSM assuming the top squark decays exclusively to a chargino and b-quark. The data is divided into three signal regions, one (1LSR) requiring only one lepton with two light-quark jets and 2 b-jets, and two (2LSR1 and 2LSR2) requiring only two leptons and two leading jets with different requirements on the minimum energy and invariant mass of the specific subsystem from the hard-scattering process. The reader is refered to the text of the paper for more details.
