Nuclear And Particle Physics Colloquium

Monday October 1, 2012 12:15 am

The Large Hadron Collider is providing our first clear view of the Terascale and is confronting our most cherished theories with data, in particular Supersymmetry. Supersymmetry arises from a symmetry allowed by nature that is simply an extension of the Poincare group. Supersymmetry at the Terascale offers attractive solutions to many outstanding issues, including the weak hierarchy problem, the dark matter problem and grand unification of the forces. Supersymmetry at the Terascale offers testable predictions that differ between models of Supersymmetry breaking. So far, LHC searches for Supersymmetry have come up short and the newly discovered Higgs-like boson is surprisingly difficult to accommodate within the simplest Supersymmetry breaking models. I will review the implications of this data on various Supersymmetric models. In particular, I will show that a region of parameter space withing the phenomenological Minimal Supersymmetric Standard Model can easily evade the LHC searches and accommodate a 125 GeV Higgs boson, while resulting in acceptable values of fine-tuning.
