Recent results from the WMAP measurements of the cosmic background radiationyield very tight constraints on the relic density of supersymmetric cold darkmatter. We combine the WMAP constraint with those from the anomalous magneticmoment of the muon and the b -> s gamma branching fraction in a chi^2determination over the minimal supergravity model (mSUGRA) parameter space. Themost favored region of mSUGRA parameter space for almost all tan(beta) valuesis the hyperbolic branch/focus point (HB/FP) region, with moderate to smallvalues of superpotential Higgs mass |mu| and large GUT scale scalar mass m_0.These favored regions of mSUGRA parameter space can be probed by direct searchexperiments for supersymmetric dark matter. An exception to the HB/FP regioncan occur at very large tan(beta) with positive mu values, where wide regionsallow resonance annihilation of neutralinos in the early universe.
