Supersymmetry: Natural or Stealth?

by Joshua Ruderman (Berkeley)

Sunrise (Fermilab)



The LHC has not found supersymmetry in the first 1/fb at 7 TeV. I will discuss where supersymmetry stands after these null results, and I will suggest promising places to look for it. The main motivation to find supersymmetry at the LHC is naturalness. Naturalness constrains the higgsinos, stops, and gluino to be light, but allows the rest of the superpartners to be heavy, including squarks of the first two generations. I will show how the 1/fb supersymmetry searches constrain natural supersymmetry by reinterpreting the experimental results. During the second part of the talk, I will introduce stealth supersymmetry: a new class of models that preserve R-parity but lack missing energy signatures. Stealth supersymmetry would be missed by regular SUSY searches, but can be discovered by looking for events with two photons and a large amount of jet HT, photon-jet-jet or 3b triple resonances, and displaced vertices.
