Dark Matter in the Finely Tuned Minimal Supersymmetric Standard Model
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 freezeout, 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 light...
متن کاملHow Finely Tuned is Supersymmetric Dark Matter ?
We introduce a quantification of the question in the title: the logarithmic sensitivity of the relic neutralino density Ωχh 2 to variations in input parameters such as the supersymmetric mass scales m0, m1/2 and A0, tan β and the top and bottom quark masses. In generic domains of the CMSSM parameter space with a relic density in the preferred range 0.1 ≤ Ωχh 2 ≤ 0.3, the sensitivities to all th...
متن کاملThe Minimally Tuned Minimal Supersymmetric Standard Model
The regions in the Minimal Supersymmetric Standard Model with the minimal amount of fine-tuning of electroweak symmetry breaking are presented for general messenger scale. No a priori relations among the soft supersymmetry breaking parameters are assumed and fine-tuning is minimized with respect to all the important parameters which affect electroweak symmetry breaking. The superpartner spectra...
متن کاملDark matter, constrained minimal supersymmetric standard model, and lattice QCD.
Recent lattice measurements have given accurate estimates of the quark condensates in the proton. We use these results to significantly improve the dark matter predictions in benchmark models within the constrained minimal supersymmetric standard model. The predicted spin-independent cross sections are at least an order of magnitude smaller than previously suggested and our results have signifi...
متن کاملThe Higgs Boson Mass at 2 loops in the Finely Tuned Split Supersymmetric Standard Model
The mass of the Higgs boson in the finely tuned Split Supersymmetric Standard Model is calculated. All 1 loop threshold effects are included, in addition to the full RG running of the Higgs quartic coupling through 2 loops. The 2 loop corrections are very small, typically less than 1GeV. The 1 loop threshold corrections to the top yukawa coupling and the Higgs mass generally push the Higgs mass...
