ABSTRACT:
I will discuss the current status of supersymmetry and three options left for weak-scale supersymmetric theories in light of the LHC data. In particular, I will present a novel broad class of supersymmetric models that preserve R-parity but lack missing energy signatures. These models have new light particles with weak-scale supersymmetric masses that feel supersymmetry breaking only through couplings to the minimal supersymmetric standard model. This small supersymmetry breaking leads to nearly degenerate fermion/boson pairs, with small mass splittings and hence small phase space for decays carrying away invisible energy. The simplest scenario has low-scale supersymmetry breaking, with missing energy only from soft gravitinos. This scenario is natural, lacks artificial tunings to produce a squeezed spectrum, and is consistent with gauge coupling unification. The resulting collider signals will be jet-rich events containing false resonances that could resemble signatures of R-parity violation. I will discuss several concrete examples of the general idea, and emphasize photon+ two jets resonances, displaced vertices, and very large numbers of b-jets as three possible discovery modes.
