Search for Leptoquarks of 1st Generation Using the ATLAS Detector

A model independent search for the production of scalar leptoquark pairs in 7TeV ATLAS data, using 1 fb-1 of integrated luminosity. Leptoquarks are hypothetical particles which carry both quark and lepton flavor, and thus, unlike any known particle, decay to both a quark and a lepton. Leptoquarks arise from many BSM theories. The channels probed in this analysis require at least one leptoquark decay to an electron, which includes the final states eejj and enujj. No excess events are observed, thus limits on allowed leptoquark mass are presented as a function of the branching fraction of the leptoquark decay to an electron and a quark.
