Dark matter direct searches and the anomalous magnetic moment of muon

Abstract In the framework of the Constrained Minimal Supersymmetric Standard Model (CMSSM) we discuss the impact of the recent experimental information, especially from E821 Brookhaven experiment on g μ −2 along with the light Higgs boson mass bound from LEP, to the dark matter direct searches. Imposing these experimental bounds, the maximum value of the spin-independent neutralino–nucleon cross section turns out to be of the order of 10 −8 pb for large values of tan β and low M 1/2 , m 0 . The effect of the recent experimental bounds is to decrease the maximum value of the cross section by about an order of magnitude, demanding the analogous sensitivity from the direct dark matter detection experiments.
