Search for light top squark pair production in final states with leptons and b-jets with the ATLAS detector in s = 7 TeV proton-proton collisions
Original language description
The results of a search for pair production of light top squarks are presented, using 4.7 fb1 of View the MathML source proton?proton collisions collected with the ATLAS detector at the Large Hadron Collider. This search targets top squarks with masses similar to, or lighter than, the top quark mass. Final states containing exclusively one or two leptons (e,?), large missing transverse momentum, light-flavour jets and b-jets are used to reconstruct the top squark pair system. Event-based mass scale variables are used to separate the signal from a large View the MathML source background. No excess over the Standard Model expectations is found. The results are interpreted in the framework of the Minimal Supersymmetric Standard Model, assuming the top squark decays exclusively to a chargino and a b-quark, while requiring different mass relationships between the Supersymmetric particles in the decay chain.
