Note that the imposition of the unified gaugino mass condition essentially imposes the requirement that there is a tiny Wino content in the LSP. The hatched region in Fig. 2 is filled in when non-unified gaugino masses are allowed. In this case, a thermal relic DM candidate can be obtained for a Bino tempered with Wino if M$_{1}$ ≈ M$_{2}$ , which implies that the SD cross section decreases, effectively filling in the region beneath the curve in Fig. 2. Note that when σ$_{SD}$ ∼ O (10 − $^{6}$pb), there is additional model dependence since the squark contribution becomes important (see Appendix A).

Finally, we note that there is a region of well-mixed Higgsino–Wino near 2 TeV with a thermal abundance (where M$_{2}$ ≈ µ ). In this case, the second line of Eq. (29) applies, and we
