TLDR
The angular dependence and the amplitude of the seasonal modulation for an isothermal halo model is calculated and it is shown that Earth's motion relative to the galactic halo produces a seasonal modulation in the expected event rate.
Abstract
If the galactic halo is composed of weakly interacting massive particles (WIMP's), then cryogenic experiments may be capable of detecting the recoil of nuclei struck by the WIMP's. Earth's motion relative to the galactic halo produces a seasonal modulation in the expected event rate. The direction of nuclear recoil has a strong angular dependence that also can be used to confirm the detection of WIMP's. I calculate the angular dependence and the amplitude of the seasonal modulation for an isothermal halo model.

Supersymmetric Dark Matter

TL;DR: In this article, the neutralino is proposed as the lightest superpartner in many supersymmetric theories, and it is shown how to calculate the cosmological abundance of neutralino and event rates for both direct and indirect detection schemes.

Non-baryonic dark matter: observational evidence and detection methods

TL;DR: The evidence for the existence of dark matter in the universe is reviewed in this paper, where a general picture emerges, where both baryonic and non-baryonic dark matter is needed to explain current observations.
