Phenomenological Hints from a Class of String Motivated Model Constructions

Figure 6

Neutralino-proton cross section for the benchmark points with successful gauge coupling unification. The colour coding is the same as in Figure 5. Models denoted by grey dots do not give the correct relic abundance for dark matter. Black, purple, and orange dots correspond to WIMP candidates that are predominantly bino, higgsino, or wino. The current limit from the LUX direct dark matter search [3] is also shown. The latter is valid if the lightest neutralino accounts for all dark matter in the universe.
