摘要：

In gauge-mediated theories supersymmetry breaking originates in a strongly interacting sector and is communicated to the ordinary sparticles via SU(3)xSU(2)xU(1) carrying ''messenger'' particles, Stable baryons of the strongly interacting supersymmetry breaking sector naturally weigh similar to 100 TeV and are viable cold dark matter candidates, They interact too weakly to be observed in dark matter detectors. The lightest messenger particle is a viable cold dark matter candidate under particular assumptions. It weighs less than 5 TeV, has zero spin and is easily observable in dark matter detectors.
