Neutralino dark matter in the supergravity and D-brane models
Supersymmetric models with conserved R-parity provide a natural candidate for dark matter, i.e. the lightest supersymmetric particle (LSP) which is stable so that it can survive the [] 15 billion years from creation in the Big Bang to present. Here we explore the possibility of supersymmetric dark matter in three models: the minimal supergravity model (mSUGRA), supergravity models with non-universal scalar soft breaking masses, and a D-brane model with three 5-branes where the SU(3)c x U(1)Y of the Standard Model reside on one five brane, 5₁, and the SU(2)[L] is on another, 5₂. In these models, the LSP, in the allowed region of the parameter space, is the lightest neutralino, [⁰̃[x₁]]. We impose constraints from cosmology for the dark matter relic density and from accelerator experimental results, i.e. the Higgs and supersymmetric particle mass bounds, the b [] branching ratio, and the muon anomalous magnetic moment, to limit the parameter space. The neutralino-proton cross section, [], is calculated for the allowed parameter space, and the result is compared to the sensitivity of current and near future detectors.
