Strong supersymmetry

Previous experiments have not found evidence for supersymmetric particles, and set limits on the mass of supersymmetric particles. However, with the high collision energies achieved at the Large Hadron Collider (LHC) the searches for these particles have entered a new realm of possibilities. This thesis describes a search for supersymmetry with the ATLAS particle detector. We search for supersymmetry by studying discrepancies from the Standard Model of particle physics in data recorded by ATLAS.
