Research Abstract

The discovery of the supersymmetry particles is highly expected in LHC-ATLAS experiment. Reconfirmation of the discovery potential with the latest detector simulation framework was conducted. In this study, the special supersymmetry signatures with energetic gamma-rays, or the long lived supersymmetric particles are explored and summarized in the paper. Since 2009.11, the commissioning of the detectors with the real collision data and the detector performance check has been carried out.
