FIG. 5: The max( σ p $_{SI}$, σ n $_{SI}$) vs. σ p SD cross sections in pb for the MSSM with gaugino mass unification. We have imposed that the thermal abundance of the neutralinos is within ± 3 σ of the WMAP measurement. We have taken the decoupling limit ( m$_{A}$ = 4 TeV). The dots (in blue) and crosses (in red) correspond to | µ | < 500 GeV and | µ | > 500 GeV respectively (see the text for a discussion). 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). sgn( Z$_{W}$ ) (see Eq. (19)) which accounts for points with the largest SI values in Figs. 3 and 4. This cannot occur in models with unified gaugino masses, where M$_{2}$ ≈ 2 M$_{1}$ . Large SI and SD signals occur as long as there is non-trivial gaugino content in the WIMP. Imposition of the thermal relic density constraint for m$_{χ}$ > m$_{W}$ , ensures a minimum required Bino component. If one imposes the large SI and SD conditions, | Z$_{B}$ | 2 ≲ 0 . 7 and | Z$_{B}$ | 2 ≲ 0 . 85 below and above the top threshold respectively. Note that the large SD requirement implies 20
