NONUNIVERSALITY EFFECTS AND DARK-MATTER IN GRAVITY MEDIATED SUSY BREAKING

Dark matter detection rates for supergravity models with R parity wher e supersymmetry is broken at a scale greater than or similar to MG are discussed. Non-universal soft breaking masses in both the Higgs and s quark sectors are considered, and it is seen that these can effect rat es by a factor of 10 - 100 when m(chi 1)-o less than or similar to 65 GeV (chi(1)(0) = Lightest neutralino) but otherwise make relatively sm all corrections. The b --> s + gamma branching ratio is seen to correl ate with detector event rates, large (small) branching ratios correspo nding to small (large) event rates. Effects of precision determination s of cosmological parameters or event rate predictions by future satel lite experiments are discussed for the Lambda CDM and the nu CDM model s.
