  5. TeV-Scale SUSY: • Fine-tuning • GUT • Dark Matter

  6. Arkani-Hamed, Dimopoulos, hep-th/0405159 Split-SUSY: • Fine-tuning • GUT • Dark Matter

  7. Split-SUSY Spectrum: • Higgs ( h ) < 150 GeV  • Higgs (H, A, H )  very heavy • Sfermion  very heavy • Gluino < 18 TeV  • Chargino/neutralino < 1 TeV 

  8. Gluino, Chargino, Neutralino < 10 TeV GUT:  F.Wang, W.Wang, JMY, hep-ph/0507172

  9. Gluino  free Dark Matter: Chargino, Neutralino < 1 TeV  F.Wang, W.Wang, JMY, hep-ph/0512133
