Phenomenological Hints from a Class of String Motivated Model Constructions

Figure 4

Parameter scan in the -plane for fixed , as described earlier in Figure 2. The blue region identifies the parameters that are compatible with the correct dark matter abundance. The vertical region around corresponds to a higgsino LSP, while the horizontal strip corresponds to (mixed) bino LSP, here at a gluino mass around 1 TeV. The gluino mass scales proportional to the gravitino mass.
