Searching for Supersymmetric Dark Matter- The Directional Rate for Caustic Rings

Abstract

The detection of the theoretically expected dark matter is central to particle physics and cosmology. Current fashionable supersymmetric models provide a natural dark matter candidate which is the lightest supersymmetric particle (LSP). The theoretically obtained event rates are usually very low or even undetectable. So the experimentalists would like to exploit special signatures like the directional rates and the modulation effect. We study these signatures in the present paper focusing on a specific class of non-isothermal models involving flows of caustic rings.
