摘要：

When the GUT relation on gaugino masses is relaxed, the mass and composition of the lightest neutralino are different from those in the GUT case. We discuss its phenomenological implications on the relic abundance of the neutralinos and on superparticle searches. In particular, we focus on the case where the neutral component of winos dominates the lightest neutralino. It turns out that the wino-LSP is not a candidate for the dark matter.
