We consider the recent limits on dark matter–nucleon elastic scattering cross-section from the analysis of CDMS II collaboration using the two signal events observed in CDMS experiment. With these limits we try to interpret the super-Kamiokande (SK) bounds on the detection rates of up-going muons induced by the neutrinos that are produced in the sun from the decay of annihilation products of dark matter (WIMP's) captured in the solar core. Calculated rates of up-going muons for different annihilation channels at SK using CDMS bounds are found to be orders below the predicted upper limits of such up-going muon rates at SK. Thus there exists room for enhancement (boost) of the calculated rates using CDMS limits for interpreting SK bounds. Such a feature is expected to represent the PAMELA data with the current CDMS limits. We also show the dependence of such a possible enhancement factor (boost) on WIMP mass for different WIMP annihilation channels.

We describe the elastic scattering of weakly interacting dark matter particles from nuclei, with laboratory detection in mind. We focus on the lightest neutralino (a neutral fermion predicted by supersymmetry) as a likely candidate and discuss the physics needed to calculate its elastic scattering cross section and interpret experimental results. Particular emphasis is placed on a proper description of the structure of the proposed detector nuclei. We include a brief discussion of expected count rates in some detectors.
