Annual modulation signature for the direct detection of Milky Way WIMP’s and supergravity models

An analysis is given of the annual modulation signal for the direct detection of relic neutralinos within the framework of supergravity unified models. It is shown that both the minimal and the non-minimal super-gravity (SUGRA) models can generate neutralino-proton cross sections at the level compatible with the signals reported by …
