FIG. 4: The max( σ p $_{SI}$, σ n $_{SI}$) vs. σ p SD cross sections in pb for the MSSM. We have imposed that the thermal abundance of the neutralinos is within ± 3 σ of the WMAP measurement. The dots (in blue) and crosses (in red) correspond to | µ | < 500 GeV and | µ | > 500 GeV respectively. The horizontal (vertical) line refers to the projected sensitivity for the next generation of SI (SD) experiments. We have shaded the near-term probeable region. Note that we are neglecting the dependence of this sensitivity on the neutralino mass. All sfermions have masses of O (2 TeV). To have non-zero SI and SD signals, a Bino-Higgsino, Wino-Higgsino or Bino-Wino-Higgsino mix is required. In fact, appreciable SI and large SD signals can be generated as long as the Higgsino fraction is larger than O (10%). Note that the | µ | < 500 GeV points, which correspond to less fine-tuning in m$_{Z}$ , imply large SD signals. When the gaugino fraction is dominated by Wino rather than Bino, the relative size of g and g ′ gives a slight enhancement in the SI cross section. There can be further enhancement of the SI cross section if sgn( Z$_{B}$ ) = 19 A. Large SI and Large SD
