A multicomponent dark matter scenario with two stable WIMPs which is consistent with the Planck observations

We review a dark matter scenario which is ideal in the sense that (1) all of the well-known successes of supersymmetry are preserved, (2) the parameters can satisfy naturalness, (3) the addition of an extended Higgs sector implies a doubly rich plethora of new particles and new physics to be discovered in the near or foreseeable future, (4) the mass of the dominant dark matter WIMP is $\le 125$ GeV/c$^2$, (5) the gauge couplings of this particle are precisely defined, and (6) naturalness implies that its Higgs-mediated couplings are also comparable to those of a natural neutralino. This scenario, with two stable spin 1/2 WIMPs (a high-mass neutralino and a more abundant "Higgson" with a mass of $\le 125$ GeV/c$^2$), is consistent with the results of Planck and othr experiments, and it also suggests that detection should be near in a variety of experiments for direct, indirect, and collider detection.
