Journal of High Energy Physics 2012(7): 196.1029-8479http://nrs.harvard.edu/urn-3:HUL.InstRepos:10718407The LHC has strongly constrained models of supersymmetry with traditional missing energy signatures. We present a variety of models that realize the concept of Stealth Supersymmetry, i.e. models with R-parity in which one or more nearly-supersymmetric particles (a “stealth sector”) lead to collider signatures with only a small amount of missing energy. The simplest realization involves low-scale supersymmetry breaking, with an R-odd particle decaying to its superpartner and a soft gravitino. We clarify the stealth mechanism and its differences from compressed supersymmetry and explain the requirements for stealth models with high-scale supersymmetry breaking, in which the soft invisible particle is not a gravitino. We also discuss new and distinctive classes of stealth models that couple through a baryon portal or Z′ gauge interactions. Finally, we present updated limits on stealth supersymmetry in light of current LHC searches.en-USsupersymmetry phenomenologyJournal Article2013-06-0510.1007/JHEP07(2012)196
