Dark Matter in the Finely Tuned Minimal Supersymmetric Standard Model
- SLAC
We explore dark matter in the Finely Tuned Minimal Supersymmetric Standard model recently proposed by Arkani-Hamed and Dimopoulos. Relative to the MSSM, there are fewer particles at freeze-out, so the calculation of the relic abundance simplifies. Similarly, the predictions for direct detection of the dark matter sharpen. There is a large region of mixed bino--higgsino dark matter where the lightest supersymmetric particle will be accessible at both the LHC and future direct detection experiments, allowing for a conclusive identification of the dark matter particle. Typical dark matter-nucleon cross sections are 10{sup -45}-10{sup -44} cm{sup 2}. This model also possesses a novel region where the dark matter annihilates via an s-channel Higgs boson resonance.
