Supersymmetry with radiatively-driven naturalness: implications for WIMP
  and axion searches
  By insisting on naturalness in both the electroweak and QCD sectors of the
MSSM, the portrait for dark matter production is seriously modified from the
usual WIMP miracle picture. In SUSY models with radiatively-driven naturalness
(radiative natural SUSY or RNS) which include a DFSZ-like solution to the
strong CP and SUSY mu problems, dark matter is expected to be an admixture of
both axions and higgsino-like WIMPs. The WIMP/axion abundance calculation
requires simultaneous solution of a set of coupled Boltzmann equations which
describe quasi-stable axinos and saxions. In most of parameter space, axions
make up the dominant contribution of dark matter although regions of WIMP
dominance also occur. We show the allowed range of PQ scale f_a and compare to
the values expected to be probed by the ADMX axion detector in the near future.
We also show WIMP detection rates which are suppressed from usual expectations
because now WIMPs comprise only a fraction of the total dark matter.
Nonetheless, ton-scale noble liquid detectors should be able to probe the
entirety of RNS parameter space. Indirect WIMP detection rates are less
propitious since they are reduced by the square of the depleted WIMP abundance.
