Abstract
his Letter presents the first search for supersymmetry in final states containing one isolated electron or pffiffi muon, jets, and missing transverse momentum from s 1⁄4 7 TeV proton-proton collisions at the LHC. The data were recorded by the ATLAS experiment during 2010 and correspond to a total integrated luminosity of 35 pb␣1. No excess above the standard model background expectation is observed. Limits are set on the parameters of the minimal supergravity framework, extending previous limits. Within this framework, for A0 1⁄4 0 GeV, tan 1⁄4 3, and " > 0 and for equal squark and gluino masses, gluino masses below 700 GeV are excluded at 95% confidence level.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
