摘要：

We survey the elastic scattering rates of neutralinos in a proposed 500 g Ge-73 + 500 g Ge-76 cryogenic detector, choosing model parameters that give a critical density of the lightest neutralino and that are currently allowed by all LEP and other accelerator constraints. We work with the full one-loop radiatively-corrected Higgs mass matrix and use grand unification relations among sfermion and gaugino masses, and we use the odd-group model to estimate nuclear matrix elements incorporating a simple model for the momentum dependence of the elastic spin and mass form factors. We find that the rates are above the 0.1 (kg d)-1 level of sensitivity of such a detector over a significant fraction of the parameter space for low values of m(A), the mass of the pseudoscalar Higgs boson.
