Relic density of dark matter in mSUGRA and non-universal SUGRA
arXiv:hep-ph/0412309
Abstract
The measurements of WMAP on the relic density of dark matter strongly constrain supersymmetric models. In mSUGRA where the neutralino LSP is mostly a bino only rather fine-tuned models survive. On the other hand the relic density upper limit can be easily satisfied in models with a Higgsino or wino LSP.
