WMAPing out Supersymmetric Dark Matter and Phenomenology

The recent WMAP data provide a rather restricted range of the Cold Dark Matter (CDM) density $\Omega_{CDM} h^2$ of unprecedented accuracy. We combine these new data along with data from BNL E821 experiment measuring ${(g_{\mu}-2)}$, the $b\to s\gamma$ branching ratio and the light Higgs boson mass bound from LEP, to update our analysis of the allowed boundaries in the parameter space of the Constrained Minimal Supersymmetric Standard Model (CMSSM). The prospects of measuring Supersymmetry at LHC look like a very safe bet, and the potential of discovering SUSY particles at a $\sqrt{s}$ = 1.1 TeV linear collider is enhanced considerably. The implications for Dark Matter direct searches are also discussed.
