A search for supersymmetry and universal extra dimensions in final states with three leptons and missing transverse momentum in 20.7 inverse femtobarns of 8 TeV pp collisions with the ATLAS detector King, Samuel
This dissertation presents a search for direct production of charginos and neutralinos in final states with three leptons and missing transverse momentum in 20.7 inverse femtobarns of 8 TeV (center of mass) proton-proton collisions delivered by the Large Hadron Collider and collected with the ATLAS detector. The Standard Model augmented with the minimal formulation of universal extra dimensions (MUED) is phenomenologically similar to supersymmetry. This search is also sensitive to MUED cascades characterized by the presence of n=1 Kaluza-Klein excitations of Standard Model W and Z bosons. No significant excess over Standard Model predictions is observed. The results are interpreted in the context of simplified supersymmetric models and MUED. New limits are set at the 95% confidence level on the parameter spaces of these models.
