Relic density of dark matter in mSUGRA and non-universal SUGRA

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.Comment: 8 pages, 3 figures, Invited talk at Physics at LHC, Vienna, July 200
