Dark Matter Generation and Split Supersymmetry
We analyze a simple Split Supersymmetry scenario where fermion masses come from anomaly mediation, yielding ms ∼ 1000 TeV, m3/2 ∼ 100 TeV, and mf ∼ 1 TeV. We find that the decay chain of moduli fields → gravitinos → LSPs generates dark matter more efficiently than perturbative freeze-out, allowing for a light, LHC visible spectrum. These decaying moduli can also weaken cosmological constraints ...
متن کاملSplit Supersymmetry and Dark Matter Generation
We analyze a simple Split Supersymmetry scenario where fermion masses come from anomaly mediation, yielding ms ∼ 1000 TeV, m3/2 ∼ 100 TeV, and mf ∼ 1 TeV. We consider non-thermal dark matter production in the presence of moduli, and we find that the decay chains of moduli → LSPs and moduli → gravitinos → LSPs generate dark matter more efficiently than perturbative freeze-out, allowing for a lig...
متن کاملDark Matter in split extended supersymmetry
We consider the split extended (N = 2) supersymmetry scenario recently proposed by Antoniadis et al. [hep-ph/0507192] as a realistic low energy framework arising from intersecting brane models. While all scalar superpartners and charged gauginos are naturally at a heavy scale, the model low energy spectrum contains a Higgsino-like chargino and a neutralino sector made out of two Higgsino and tw...
متن کاملDark Matter Constraints on Gaugino/Higgsino Masses in Split Supersymmetry and Their Implications at Colliders
In split supersymmetry, gauginos and Higgsinos are the only supersymmetric particles which are possibly accessible at foreseeable colliders. While the direct experimental searches, such as LEP and Tevatron experiments, gave robust lower bounds on the masses of these particles, the cosmic dark matter can give some upper bounds and thus have important implications for the searches at future colli...
متن کاملIndirect Signals from Dark Matter in Split Supersymmetry
We study the possibilities for the indirect detection of dark matter in Split Supersymmetry from γ-rays, positrons, and antiprotons. The most promising signal is the γ-ray line, which may be observable at the next generation of detectors. For certain halo profiles and a high mass neutralino, the line can even be visible in current experiments. The continuous γ-ray signal may be observable, if t...
