This seminar focuses on the search for weakly produced supersymmetric particles (particularly charginos and sleptons) in the ATLAS experiment at the LHC using events with exactly two reconstructed leptons. This analysis was first performed using the 2011 dataset and an extension based on 2012 data was performed earlier this year. The motivation for such searches will be presented, and the analysis technique outlined. Because of the low signal cross sections for weak production processes, high background suppression is required, and in both the 2011 and 2012 analyses the sensitivity is driven by signal regions based on the “stransverse mass variable”, which will be described in the seminar. Finally, the results of the latest search will be presented and discussed.
