  1. Dark Matter Constraint on Split-SUSY & Implication at Colliders Jin Min Yang Institute of Theoretical Physics, CAS Wang, Wang, Yang, hep-ph/0512133 EPJC 46, 521(2006)

  2. Outline： 1、 SUSY Dark Matter Introduction 2、 SUSY & Split-SUSY 3、 Dark Matter Constraint on Split-SUSY 4、 Implication at LHC & ILC 5、 Conclusion

  3. 1、 SUSY Dark Matter Dark Matter Mass:weak-scale Interaction: weak-scale WIMP

  4. LSP  Dark Matter

  5. Which one is LSP ? LSP ?

  6. LSP

  7. 2. SUSY & Split-SUSY Weak-Scale SUSY • Fine-tuning • GUT • Dark Matter Split-SUSY

  8. SUSY Zoo: h, H (CP-even) Higgs Bosons A (CP-odd) H squarks sfermions sleptons Sparticles gluino sauginos higgsinos charginos neutralinos

  9. Low-energy SUSY (MSSM): All sparticles < TeV 1 < 130 GeV 5 Higgs bosons 4 < TeV

  10. Split-SUSY: Gauginos/Higgsinos < TeV Super Particles Others：superheavy 1 < 150 GeV Higgs Bosons 4：superheavy

  11. SUSY Higgs Bosons at LHC: one: in Split-SUSY Discover  one: in MSSM

  12. MSSM LHC sfermions sparticles LHC gauginos higgsinos ? LHC Split-SUSY

  13. GUT with split-SUSY:

  14. 3. Dark matter constraint on Split-SUSY neutralino: dark matter neutralino freeze-out charginos dark matter constraint neutralinos

  15. Neutralino annilation:

  16. WMAP 2

  17. 4、 Implication at LHC & ILC + pp  - 1 1 e+e-  + - 1 1

  18. 5、 Conclusion Higgs bosons sparticles h H, A, Hsfermions gaugino/Higgsino SM  MSSM     Split-SUSY   ???
