Gaseous dark matter detectors

Abstract

Dark matter (DM) detectors with directional sensitivity have the potential of yielding an unambiguous positive observation of WIMPs as well as discriminating between galactic DM halo models. In this paper, we introduce the motivation for directional detectors, discuss the experimental techniques that make directional detection possible, and review the status of the experimental effort in this field. © IOP Publishing Ltd and Deutsche Physikalische Gesellschaft.
