Abstract
Event rates for neutralino-nucleus scattering are studied including the constraint arising from the recent CLEO results on b→sγ using the cold hot dark matter (CHDM) model. It is found that the CLEO results strongly affect the supersymmetric spectrum and the event rates. The analysis given here uses the accurate method for the computation of the relic density and leads to a dip in the event rate when the neutralino mass is ∼MZ/2 due to the Z pole and ∼mh/2 due to the Higgs pole. The effect of the new Δq determinations on event rates is also discussed.
