N2 - By eschewing fine-tuning from the electroweak and QCD sectors of supersymmetry (natural supersymmetry or SUSY), and by invoking the Kim-Nilles solution to the SUSY μ problem, one is lead to models wherein the dark matter is comprised of a mixture of axions and Higgsino-like WIMPs. Over a large range of Peccei-Quinn breaking scale fa∼109-1012 GeV, one then expects about 90%-95% axion dark matter. In such a scenario, both axion and WIMP direct detection may be expected.
