Description:

The lack of evidence for SUSY at the LHC motivates new search strategies such as looking for scenarios with small mass differences between SUSY particles.  However, this can bring challenges because of lower momentum visible decay products.  SUSY searches with two leptons offer the possibility to use unique shapes in the invariant mass spectrum as an additional discriminant.  In this talk, I will go through the details of ATLAS SUSY searches with two leptons, and show some highlights of recent SUSY results.  Additionally, I will discuss how track triggers can enhance the discovery reach of these searches, focusing on the ATLAS Fast TracKer as an example along with its Phase-II counterpart.
