DescriptionWe present a search for the production of three or more isolated leptons in proton–proton collision data at√s=7TeV, corresponding to an integrated luminosity of4.98fb−1, that was collected by the CMS detector during the 2011 LHC run. Thepossible final states are classified according to a number of physical properties toproperly account for varying Standard Model backgrounds and signal yields. Several super symmetric (SUSY) models that yield multi-lepton events are investigated, andmass exclusions along with cross-section upper limits are presented for anR-parityconserving co-NLSP model, anR-parity violating model (both from strong SUSY pro-duction) as well as for several SUSY topologies that lead to electroweak pair productionof charginos and neutralinos which then decay to multi-lepton final states. No new physics was observed.
