[SLAC] [SLAC Pubs and Reports] SLAC-PUB-7131Higgsino Cold, Dark Matter Motivated by Collider Data Abstract Motivated by the supersymmetric interpretation of the CDF $ee\gamma\gamma + \slashchar{E}_T$ event and the reported $Z\to b\bar b$ excess at LEP, we analyze the Higgsino as a cold dark matter candidate. We examine the constraints as implied by the collider experiments, and then calculate its relic density. We find that this Higgsino-like lightest supersymmetric particle is a viable cold dark matter candidate ($0.05< \Omega h^2 < 1$), and we discuss its favorable prospects for laboratory detection.
