Nucleon scattering with Higgsino andW-ino cold dark matter

Neutralinos that are mostly W-ino or Higgsino are shown to be compatible with the recent DAMA annual modulation signal. The nucleon scattering rates for these dark matter candidates are typically an order of magnitude above the oft-considered B-ino. Although thermal evolution of Higgsino and W-ino number densities in the early universe implies that they are not viable dark matter candidates, nonthermal sources, such as from gravitino or moduli decay in anomaly-mediated supersymmetry breaking, suggest that they can be the dominant source of cold dark matter. Their stealthiness at high energy colliders gives even more impetus to analyze nucleon scattering detection methods. We also present calculations for their predicted scattering rate with germanium detectors, which have yet to see evidence of WIMP scattering.
