Sensitivity for the Discovery of Supersymmetry in the Leptons plus Jets

Preparations are underway to search for possible signatures of Supersymmetry (SUSY) in the inclusive leptons plus jets and missing transverse energy (MET) as well as semi-inclusive topologies involving same-sign dimuon final states, using the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider. This talk reports on the expected performance of CMS, using a full simulation of the detector, and studies its effect on SUSY discovery potential. The primary background sources to SUSY are expected to arise from QCD mulitjets, top anti-top, and W/Z production. Strategies for reducing this background, both from the online CMS trigger and from offline data analysis, as well as understanding and controlling systematic uncertainties, are presented.
