NEUTRALINO DARK-MATTER IN NONUNIVERSAL SUSY MODELS

The properties of neutralino dark matter in the context of different s upergravity schemes are reviewed. In particular, we discuss the effect s induced by the relaxation, at the grand unification scale, of the so ft scalar mass universality on the supersymmetric parameter space, on the neutralino relic abundance, and on the event rates for direct and indirect detection of relic neutralinos.
