Supersymmetry Breaking, Extra Dimensions and Neutralino Dark Matter
نویسنده
چکیده
We show some phenomenological implications for the dark matter problem of a class of models with deflected anomaly mediated supersymmetry breaking in the context of the MSSM. This scenario can be naturally embedded in a brane world model with one compactified extra dimension. It turns out that in these models the neutralino is still the LSP and so a good candidate as cold dark matter. We found that the neutralino is quite a pure bino in almost all the parameter space. Moreover we computed the thermal relic density and we found wide cosmologically allowed regions for the neutralino.

Building a Better mSUGRA: WIMP Dark Matter Without Flavor Violation
The appearance of a natural dark matter candidate, the neutralino, is among the principal successes of minimal supergravity (mSUGRA) and its descendents. In lieu of a suitable ultraviolet completion, however, theories of gravity-mediated supersymmetry breaking such as mSUGRA suffer from arbitrary degrees of flavor violation. Though theories of gauge-mediated supersymmetry breaking are free from...
متن کاملOn Supersymmetric Dark Matter
The extra particles provided by Supersymmetry(SUSY) appear as natural candidates for exotica such as the missing Dark Matter of the Universe. The particle candidates for Dark Matter, and the basic elements of the minimal supersymmetric extension of the Standard Model are reviewed. The needed elements to compute the neutralino counting rate are given, considering new Yukawa loop corrections to t...
متن کاملDark Matter from Gaugino Mediation
We study dark matter for gaugino-mediated supersymmetry breaking and compact dimensions of order the grand unification scale. Higgs fields are bulk fields, and in general their masses differ from those of squarks and sleptons at the unification scale. As a consequence, at different points in parameter space, the gravitino, a neutralino or a scalar lepton can be the lightest (LSP) or next-to-lig...
متن کاملDirect and Indirect Detection of Neutralino Dark Matter In Selected Supersymmetry Breaking Scenarios
Various methods of searching for supersymmetric dark matter are sensitive to WIMPs with different properties. One consequence of this is that the phenomenology of dark matter detection can vary dramatically in different supersymmetric breaking scenarios. In this paper, we consider the sensitivities to supersymmetric dark matter of different detection methods and techniques in a wide variety of ...
متن کاملTwo universal extra dimensions and spinless photons at the ILC
We study the ILC phenomenology of (1,0) Kaluza-Klein (KK) modes along two universal extra dimensions compactified on the chiral square. We compute production cross sections of various (1,0) particles at the ILC with √ s = 1 TeV, focusing on decays of KK-leptons and the KK partner of hypercharge gauge boson down to the " spinless photon " which is the lightest KK particle. We contrast this model...
