Abstract
The case for a stable population of solar-bound Earth-crossing weakly interacting massive particles (WIMPs) is reviewed. If such a population exists, even with a conservative phase-space density, the next generation of large-mass, low-threshold underground bolometers should bring about a sizable enhancement in WIMP sensitivity. A practical general expression for their speed distribution in the laboratory frame is derived under basic model-independent assumptions, and a characteristic yearly modulation in their recoil signal, arising from the ellipticity of the Earth’s orbit, is presented.Keywords
