Phys. Rev. Lett. 76, 4458–4461 (1996)Higgsino Cold Dark Matter Motivated by Collider DataReceived 21 March 1996; published in the issue dated 10 June 1996 Motivated by a supersymmetric interpretation of the CDF eeγγ+ET event and the reported Z→bb̅ excess at LEP, we analyze the implied Higgsino-like lightest supersymmetric partner as a cold dark matter candidate. We examine constraints and calculate its relic density, obtaining 0.05<Ωh2<1. Thus it is a viable cold dark matter candidate, and we discuss its favorable prospects for laboratory detection. © 1996 The American Physical Society URL:
