【 摘 要 】

In this report senior investigator Prof. Milind V. Purohit describes research done with data from the ATLAS experiment at CERN. This includes preparing papers on the performance of the CSC detector, searches for SUSY using a new modern ''big data'' technique, and a search for supersymmetry (SUSY) using the "zero leptons razor" (0LRaz) technique. The prediction of the W=Z+jets background processes by the ATLAS simulation prior to the fit is found to be overestimated in the phase space of interest. In all new signal regions presented in this analysis the number of events observed is consistent with the post-fit SM expectations. Assuming R-parity conservation, the limit on the gluino mass exceeds 1150 GeV at 95% confidence level, for an LSP mass smaller than 100 GeV. Other USC personnel who participated in this project during the period of this grant were a graduate student, Anton Kravchenko.
