Resumen:
We present an update of a search for supersymmetry in final states
containing jets, missing transverse momentum, and one isolated electron
or muon, using 1.04 fb^-1 of proton-proton collision data at sqrt{s} = 7
TeV recorded by the ATLAS experiment at the LHC in the first half of
2011. The analysis is carried out in four distinct signal regions with
either three or four jets and variations on the (missing) transverse
momentum cuts, resulting in optimized limits for various supersymmetry
models. No excess above the standard model background expectation is
observed. Limits are set on the visible cross-section of new physics
within the kinematic requirements of the search. The results are
interpreted as limits on the parameters of the minimal supergravity
framework, limits on cross-sections of simplified models with specific
squark and gluino decay modes, and limits on parameters of a model with
bilinear R-parity violation.
