Scientific paper

We study the direct detection rate for SUSY cold dark m atter (CDM) predicted by the minimal supersymmetric standard model with universal boundary conditions and large values for tan\beta. The relic abundance of the lightest supersymmetric particle (LSP), assumed to be approximately a bino, is obtained by including its coannihilations with the next-to-lightest supersymmetric particle (NLSP), which is the lightest s-tau. We find detectable rates in the currently planned experiments for a sector of the parameter space consistent with the cosmological constraint on the LSP relic abundance and the ones imposed by b->s gamma and the Higgs searches.
