Phenomenological Hints from a Class of String Motivated Model Constructions

Figure 2

Parameter scan in the -plane for fixed . The regions where the gauge couplings unify within the experimental error on the strong coupling are shown in green. In the upper region, the lightest neutralino is predominantly of bino-type, where the lower one corresponds to a wino-like LSP. The red region exhibits a gluino LSP. The dotted contour indicates where the mass ratio between gluino and LSP becomes two.
