Dark matter in the finely tuned minimal supersymmetric standard model

We explore dark matter in the Finely Tuned Minimal Supersymmetric Standardmodel recently proposed by Arkani-Hamed and Dimopoulos. Relative to the MSSM,there are fewer particles at freeze-out, so the calculation of the relicabundance simplifies. Similarly, the predictions for direct detection of thedark matter sharpen. There is a large region of mixed bino--higgsino darkmatter where the lightest supersymmetric particle will be accessible at boththe LHC and future direct detection experiments, allowing for a conclusiveidentification of the dark matter particle. Typical dark matter-nucleon crosssections are 10^{-45}-10^{-44} cm^{2}. This model also possesses a novel regionwhere the dark matter annihilates via an s-channel Higgs boson resonance.Comment: 13 pages, 2 figures. Fixed minor typo.
