Dark Matter Detection in Focus Point Supersymmetry
We determine the prospects for direct and indirect detection of thermal relic neutralinos in supersymmetric theories with multi-TeV squarks and sleptons. We consider the concrete example of the focus point region of minimal supergravity, but our results are generically valid for all models with decoupled scalars and mixed Bino-Higgsino or Higgsino-like dark matter. We determine the parameter sp...
متن کاملNeutralino Dark Matter in Focus Point Supersymmetry
In recent work, it has been argued that multi-TeV masses for scalar superpartners are not unnatural. Indeed, they appear to have significant phenomenological virtues. Here we explore the implications of such ‘focus point’ supersymmetry for the dark matter problem. We find that constraints on relic densities do not place upper bounds on neutralino or scalar masses. We demonstrate that, in the sp...
متن کاملNeutralino Dark Matter Detection in Split Supersymmetry Scenarios
We study the phenomenology of neutralino dark matter within generic supersymmetric scenarios where the Gaugino and Higgsino masses are much lighter than the scalar soft breaking masses (Split Supersymmetry). We consider a low-energy model-independent approach and show that the guidelines in the definition of this general framework come from cosmology, which forces the lightest neutralino to hav...
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 in gravity-mediated supersymmetry breaking
Astrophysicists have long been telling us that the universe is mostly made up of dark matter. Modern analyses, which take into account the subtleties of large scale structure formation, big bang nucleosynthesis, and observations of how galaxies rotate, have largely condensed to one common conclusion: most of the dark matter is probably stable weakly interacting massive particles (WIMPs) [1]. Wh...
