Supersymmetric dark matter in light of WMAP

Year: 2003

Type: article

Abstract: We re-examine the parameter space of the constrained minimal supersymmetric extension of the Standard Model (CMSSM), taking account of the restricted range of ΩCDMh2 consistent with the WMAP data. This provides a significantly reduced upper limit on the mass of the lightest supersymmetric particle LSP: mχ≲500 GeV for tanβ≲45 and μ>0, or tanβ≲30 and μ<0, thereby improving the prospects for measuring supersymmetry at the LHC, and increasing the likelihood that a 1-TeV linear e+e− collider would be able to measure the properties of some supersymmetric particles.
