| Description | Joint Theory Seminar Speaker: Matt Reece Title: Low-Scale SUSY Breaking: Collider Physics and Cosmology Host: John Terning Room: 432 Abstract: In this talk I will discuss some distinctive phenomenology associated with low-scale breaking of supersymmetry (as in models of gauge mediation). I will explain some possible collider signatures at the LHC of long-lived neutralino NLSPs, which can decay to a Z or Higgs boson plus a gravitino on timescales of order the size of the detector. I will also argue that, without fine-tuning, low-scale breaking of supersymmetry will generically be associated with the presence of light moduli fields that pose cosmological problems. I will discuss how incorporating a QCD axion in this framework might lead to a relatively natural solution of these moduli problems, and how it might also be associated with exotic collider signatures involving axinos or other new weakly-coupled particles. |
