Supersymmetric Dark Matter

Abstract

A review of supersymmetric dark matter in minimal supergravity unification with R-parity invariance and with radiative breaking of the electro-weak symmetry is given. The analysis shows the lightest neutralino is the LSP over most of the parameter space of the supergravity model. The event rates in neutralino- nucleus scattering in dark matter detectors are also discussed.It is found that the event rates are sensititive to the constraint from the $b\rightarrow s\gamma$ experiment.It is also found that the event rates are sensitive to the constraints of relic density and in our analysis we have used the accurate method for the computation of the neutralino relic density. Finally,the effect of the new results on quark polarizabilities, from the data of the Spin Muon Collaboration, on event rates is also discussed.The analysis shows that the event rates for the Ge detectors and for other detectors which use heavy targets are only negligibly affected.
