摘要：

Motivated by a supersymmetric interpretation of the CDF ee gamma gamma + E(r) event and the reported Z --> <b(b)over bar> 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 < Omega h(2) < 1. Thus it is a viable cold dark matter candidate, and we discuss its favorable prospects for laboratory detection.
