Updating the constraints to CMSSM from cosmology and accelerator experiments

The recent data from E821 Brookhaven experiment in conjunction with a new determination of the hadronic vacuum polarization contribution to the anomalous magnetic moment of muon, put new bounds on the parameters of the Constrained Minimal Supersymmetric Standard Model. We study the impact this experimental information, along with the $b \goes s \gamma$ branching ratio and light Higgs boson mass bound from LEP, to constrain regions of the model which are consistent with the cosmological data. The effect of these to Dark Matter direct searches is also discussed.
