Scientific paper

In the frame of an effective MSSM model without gaugino-mass unification at a grand unification scale, we set a lower bound on the neutralino mass based on the WMAP data on ΩCDM. We then discuss the prospects of detection of the light relic neutralinos which arise in this class of models; they can provide detectable rates in direct detection experiments and a detectable antiproton flux from annihilation in the galactic halo. The gamma-ray signal can reach detectable levels only for strong singular dark matter density profiles.
