Resumen:
A search for supersymmetric particles in final states with zero, one,
and two leptons, with and without jets identified as originating from b-quarks, in 4.7 fb−1 of
s√=7 TeV
pp collisions
produced by the Large Hadron Collider and recorded by the ATLAS
detector is presented. The search uses a set of variables carrying
information on the event kinematics transverse and parallel to the beam
line that are sensitive to several topologies expected in supersymmetry.
Mutually exclusive final states are defined, allowing a combination of
all channels to increase the search sensitivity. No deviation from the
Standard Model expectation is observed. Upper limits at 95 % confidence
level on visible cross-sections for the production of new particles are
extracted. Results are interpreted in the context of the constrained
minimal supersymmetric extension to the Standard Model and in
supersymmetry-inspired models with diverse, high-multiplicity final
states.
