Title: Going Beyond Traditional SUSY Searches

Abstract: Many searches for supersymmetry (SUSY) have been performed with the LHC data, and so far, none has found any signs of physics beyond the standard model. A theme common to many of these searches is the reliance on the presence of substantial missing transverse momentum (MET) from undetected SUSY particles. It is therefore reasonable to wonder whether SUSY could take a form that instead produces low-MET final states, thereby evading detection in standard searches.

In this seminar I will first discuss the motivation and strategy behind traditional SUSY searches, using the CMS search for top squarks in the all-hadronic final state as an example. Then, I will introduce SUSY models that lead to low-MET top squark decays including stealth SUSY and R-parity violating SUSY.  Finally, I will describe a strategy for searching for new physics in the challenging final state with top quarks and low MET.
