Research Abstract

Although Supersymmetry is the most promising theory beyond the Standard Model, no direct evidence had been found before starting the LHC experiments. In this research, direct searches have been made using the initial data taken with ATLAS detector at the LHC. Installation, operation, maintenance, and calibration of the muon trigger system of the ATLAS detector have been also carried out.
