Direct Search of Dark Matter in High-Scale Supersymmetry
read the original abstract
We study direct detection of dark matter in supersymmetric (SUSY) model where most of SUSY particles have very high-scale masses beyond the weak scale. In the scenario, Wino-like or Higgsino-like neutralino is a good candidate for the dark matter in the universe. The neutralino scatters off nuclei by a Higgs-boson exchange diagram and also electroweak loop diagrams. It is found that the elastic-scattering cross section with nuclei is enhanced or suppressed due to constructive or deconstructive interference among the diagrams. Such a cross section is within the reach of future experiment in some parameter region.

Complementary Probes of Light Higgsinos: Electroweak Precision Measurements and Dark Matter Direct Detection
Future electroweak precision measurements can probe light higgsinos up to 500 GeV even in compressed spectra below the neutrino fog, complementing direct detection which reaches the 1 TeV thermal relic mass.
