MUON ANOMALOUS MAGNETIC MOMENT, B → X_Sγ AND DARK MATTER DETECTION IN THE STRING MODELS WITH DILATON DOMINATION

We consider the string models with dilaton domination in the intermediate string scale. After imposing the direct search limits on the lightest neutral Higgs and SUSY particle masses and the lightest neutralino LSP, the is predicted to be less than 55 × 10⁻¹⁰ for M_string = 3 × 10¹¹ GeV. If we further impose the B → X_sγ branching ratio, the predicted becomes lower to 35 × 10⁻¹⁰. The resulting LSP - proton scattering cross section is not larger than ~ 10⁻⁷ pb which is below the sensitivity of the current direct dark matter search experiments, but future experiments can cover this.
